Community Blogging with Stephen Downes

He wants reframe our thoughts on what a community is, what it constitutes online and in the blog world.

What usually enables a community in the real world is proximity. In the online version, it is a “place” online. The traditional model was to give them a site, a topic, they will talk and you can retire to the Caymans.

In online learning- there is an assumption that it happens in a learning management system, or learning content management system.

In social networking sometimes it’s Orkut, Friendster, even Flickr.

These are all places, not communities.

Two major elements that define “community”.

1. The network- idea that there is some connection between people, they is understood
2. The semantics- it’s about something, a topic, a value, an interest

Against the long tail- a property of networks. Get a bunch of people getting together and linking, what you get is a group of links. Similar to six degrees ideas. What happens is that some get lots of links, some get just a few. The power law is about the small group getting a lot links and a very large group getting only a few.

Conditions for Power Laws

1. Growth- the network grows over time
2. preferential attachment- nodes with a high degree are more likely
Base metaphor: the rich get richer

People endlessly talk about the virtues of the long tail- these are inevitably people who are living in the long tail.

Preferential attachment occurs because there is a shortage of time, money, attention of resources. It occurs at random. Often it is because something is available, not just good.

Community is based in meaning, not randomness
Community as proximity= random connections
Community as networks of semantic relations= semantically based connections

To build community, you don’t pick the random available connections, you pick the most salient.

Stephen is anti-tagging. What would a graph of all the tags for a subject look like? A power law. The meaning of the post becomes whatever is at the spike of the power law.

Two ways of looking at the world: Two modes of cognition

1. Seeing the words
2. Seeing the patterns

How do we kill the big spike?

What is happening is a transformation on online learning from a centralized, institution-based system with a top-down structure to a bottom up grassroots structure.

Community is defined by

Means of organizing input and experience
Means of putting that experience into context
Means of creation, of becoming part of someone else’s experience
There is no “place that represents communities with a variety of self-selected relations using a variety of contextual information to establish meaning. Meaning emerges from the community rather than defining community.
…

I missed some sections and got lost in the presentation. Some of Stephen’s ideas went a little over my head. I’m just not into the academic discussions I guess, or maybe I'm not smart enough to get it.

I was also disappointed to see him group 43 Things with some of the famous inauthentic deceptions in the blog history. People are jumping on them because they got a lot of investment from Amazon- it doesn’t mean they are being devious, inauthentic or evil. They just didn’t announce the Amazon connection soon enough. There is a short discussion here with a comment from Josh Peterson on the matter.

Thanks for the notes!

Stephen Downes on Community

I've seen Stephen slag us on his blog with no sort of accuracy in his claim that we aren't somehow "real". I'm not sure what his beef is, but it is somewhat amusing in that 43 things meets all his acadmic definitions - and is the outgrowth of thinking about what doesn't work in online learning tools. Apparently he even had us in his slides, but decided to slander rather than fact check. I have faith that the blogosphere will set this right.

I'm a political theorist by academic training and have spent lots of time thinking and teaching about ideas as to how communitites are constituted, constructed, and governed - and I've worked on online community related systems since 1996. So I'm sympathetic to Mr. Downes line of thought, if not his pronouncements about 43 things. But, whatever, if Flickr isn't one either, than I don't want to be either.

Stephen Downes on Community

Thanks for these notes. I'm very disapointed not to be there.

Thanks also to keep us informed about 43 things and what Stephen Downes Think of it.

I personnaly think that's an extraordinary "object/project to think with".

Stephen Downes on Community

Of the 8300 or so posts I have written over the years, I have addressed one to 43 Things. Here it is; the reader can decide whether I have been slagging or slandering 43 Things:

"43 Things Amazon Conspiracy
There was a social networking meme that went around a few weeks ago called '43 Things' - the idea is that you would form online groups dedicated to doing one of the 43 things would would like to do. I thought it was interesting but not really applicable to online learning, so I didn't cover it here. Now I sort of wish I did, but am glad I didn't, because it turns out that the whole thing was a front for Amazon.com. Well. I don't know what to think, except to observe that companies are becoming increasingly sophisticated in their online efforts. And it is becoming increasingly difficult to distinguish between a genuine grassroots movement and a marketing campaign. Meanwhile, I'll classify this story about 43 Things under the heading: funny. By Jason Kottke, Kottke.org, February 10, 2005."

The title is Kottke's, and I link to his article, which in turn links to the Salon article where the story broke. Link

I also mentioned 43 Things in my talk. Here is what the slide said (the slides are available here)

"Educational ‘Communities’
This is ‘community’ as defined in the educational works:
Subjects defined as nice neat trees of topics
People organized into schools, classes
The presentation of meaning ‘top down’; community defined by conformance
Ripe for abuse – propaganda, marketing – astroturf, 43 things, Raging Cow, the Lincoln Fry, WSJ Opinion"

And three links, to Dan Gillmor, one of my own articles and J.D. Lasica.

Here is what I said as I presented this slide (at 30:11 in my talk - the MP3 is available here ): "Educational communities the old way - nice neat topics, classes and so on - but this kind of structure both in schools and in the blogosphere where you have the flow coming from the top is ripe for abuse. And there's another one from J.D. Lasica just came out today, "Influence Peddling in the Blogosphere." And of course we heard mention earlier of Raging Cow and the Lincoln Fries. Eventually these companies are going to get good at this. Right now they're screamingly bad. But they are eventually going to bcome good. 43 Things had the entire blogosphere fooled for a couple of weeks. And... and it sort of fell apart. Eventually there will be things that don't fall apart. I look at the Wall Street Journal opinion columns and they are defining from the top down. There's a whole bunch of people out there who echo the words that they see in these opinion columns. They don't know what they mean because there is no context. They're just echoing the words. It just becomes a way for the Wall Street Journal to broadcast."

So did 43 Things do what I said? Well, let's look. According to the 43 Things site (dated February 8, 2005): "As we congealed around what we were building and how it might come together, I started conversations with various people in a position to help. I spoke with folks at Amazon (I worked there from 1996-2001, and Microsoft from 2002-2004) as well as several other angel investors and VC firms. We decided to self fund until we worked out a deal with Amazon.com. That came together in the Fall of 2004." Link

OK, then, so when did the rest of the world get to know about this? The Robot Coop blog makes the announcement February 7: "Amazon.com has invested in The Robot Co-op. We think it will get easier to meet our goal to Start a company that survives longer than 2 years though we still have lots of work to do." Sounds like it just happened, doesn't it? Link

So what prompted this flurry of disclosure February 7-8? Probably this: "When Salon asked Erik Benson, the 'chief janitorial officer' of the Robot Co-op, if his company is a subsidiary of Amazon, he said: 'Can I get back to you on that?' When pressed, he said the company is going to announce an investment from Amazon next month. But he wouldn't say if his company would be wholly owned by Amazon, or if the shopping site would just be one of several investors. 'Nobody's supposed to know that,' he said." Salon, February 8, 2005. Link

Now I had encountered 43 Things a couple of weeks before. I created my account on the site. Link And I joined a couple of Things'. Link
So I had had a good look at the site.

Then, as now, there is utterly no mention of Amazon.com on the 43 Things site. Check for yourself. Link

Same with the Robot Coop site. No mention of Amazon anywhere on the page design, no mention of the Amazon funding until February 7, 2005 - well after the fall of 2004.

So 43 Things was funded by Amazon for months before it was announced. And there was no way for the 10,000 users (as of February 5) to have known.

Was this a deliberate policy? Judge for yourself. Link

"I’m dumb but I did not understand: how happened that dave gave this talk?
Did he call up amazon saying “guys I’ve got thus funny thing I have to show you!” ?
— gabriele renzi Oct 10, 6:16am #"

"Amazon regularly has people come by and give talks. I think Dave was going around doing a bunch of talks about Ruby, and Amazon sort of fit into his schedule. That’s my guess at least.
— Erik Benson Oct 12, 4:39pm #"

I stand by what I said.

Sounds like you had a lot to say. You are certainly welcome to your opinion, but you don't really explain how taking an investment makes a company a front or astroturf. Sure, we didn't talk about any of the funding. Not the self funding, not the investment, until someone wrote to a reporter with the story. Does that make us a front for someone else? The truth is, it was just private business, and it doesn't change what we are building.

You are going around telling a story that simply isn't true. Is every company a front for its investors? No one was trying to fool anyone, the content on our site is there for the whole internet to see. And if you talked to folks like Lee, you could talk to someone who knows us, was at my house hearing about the plans early on, saw our offices when we were just moving out of the basement, etc. How does that make us astroturf? You don't explain. You are just calling people names. That's rude in my neighborhood. I truly don't grasp the namecalling But cheers! Make community however you choose.

Stephen Downes on Community

So putting aside your hard-on over 43 Things (not a fight I'm interested in), how do you propose to revoke the laws of mathematics & do away with the Long Tail of scale-free networks?

Tim

Stephen Downes on Community

It's not a fight I'm interested in either, your superfluous sexual metaphor to the contrary notwithstanding.

Here is a network that does not display a power law.

I can draw many more networks which do not display power law relations, as will be obvious from the diagram.

Did I just break the law of mathematics? No. Power laws develop only under certain conditions, which I describe in my talk.

Change the conditions - as I proposed - and you change the power law.

So why do we see so many power laws in nature?

Nature follows the easiest path - that's what selective attraction is all about. When forming a new connection, pick what appears to be the first available link.

Nature's path may be easiest, but it is not meaningful - the first available link might be the best, the worst - who knows? Because, for all intents and purposes, its selection is random.

My proposal is to apply constraints to the link selection by using social network data in RSS feeds. Constraints tend to reduce the size of the big spike. You can apply constraints by either (a) limiting the number of links a big spike can get (this is what happens in, eg., airline networks, where there is an upper limit to how many flights a hub can service) or (b) increasing the probability of selecting a 'long tail' link (this is what happens when you have limited connectivity outside your community - which is why the ebola virus didn't spread).

My proposal is a mixture. By adding an 'A knows B' element to linking, I (a) make links to big spikes less likely, because it is hard for a person to know more than a few hundred people, and (b) make 'long tail' links more likely, because the people you know are more likely to be members of the long tail.

Because the constraint I apply is meaningful - because it reflects the sense and context of the resource in question - the resulting network structure is also meaningful.

The consequent reduction of the big spike has the benefits I describe in my paper .

Stephen Downes on Community

Several metaphors jump to my mind.

First, you're setting up a strawman when you talk about avoiding random connections, which I don't think anybody's in favor of. Nobody I know throws a die to decide which link to follow or which new blog to read. Fitness (salience) is always a consideration, although there may be limited ability to meaningfully differentiate. The point is that structure develops even if you do choose randomly (which nobody in the real world does).

Second, I think you're either tilting at a windmill, plugging your finger in the dike or pushing back the tide (take your pick!) in trying to stomp out or reshape power-law curves. Of course there are other topologies than scale-free (random, log-normal, small-world), but trying to shoehorn what naturally develops one way into an artificial topology is bound to be energy-intensive & ultimately likely futile.

Third, I've run out of metaphors but it looks to me like you're completely ignoring the proven value of long-range links to the health, stability & innovative power of a network. It's these connections that bring a fresh perspective into situations that've become stale or deadlocked. Ah, there's more metaphors after all - you're either missing the boat, missing the forest for the trees or cutting off your nose to spite your face.

Here's three examples of social networks that've become pathological due to their emphasis on salience: Free Republic, Little Green Footballs & Democratic Underground.

Tim

Stephen Downes on Community

Regarding the first two points: "Fitness (salience) is always a consideration..." , and "trying to shoehorn what naturally develops one way into an artificial topology is bound to be energy-intensive & ultimately likely futile."

It seems to me you can't have both points. It sounds like you're saying that people do take salience into consideration, but that I shouldn't because it's pointless.

The heart of the question is, of course, is whether (a) the current distribution is more natural than what I propose, and (b) whether being more natural is inherently better.

I respond in the negative on both points. The current order is an artifact of an artificial construction, the structure of content syndication networks as they were originally conceived by Tim Berners-Lee, Netscape and Dave Winer. It is no more or less natural than a network that could have been constructed slightly differently, say, by including 'DC:creator' tags in RSS files.

Even if it were more natural, it doesn't follow that it is better. Most human activity falls into the realm of the non-natural, including flight, artificial sweetener, categorization and atonal music. What humans do, uniquely, that is non-natural is add meaning to otherwise meaningless phenomena. That's how a piece of paper in your wallet can be translated into a burger.

Now for the third point. You write, "it looks to me like you're completely ignoring the proven value of long-range links..."

I disagree. Nothing I have written speaks against long-range links. It speaks only against the concentration of such links into hubs.

Finally, as to the fourth point: "Here's three examples of social networks that've become pathological due to their emphasis on salience..."

While I agree with your assessment of these sites, I would point out that they are not networks as I am proposing, and that indeed each is an instance of the centralized site-based network that I argued against, and that when I said that abuse was possible and likely possible in centralized networks, these would be three very good examples of what I meant.

Stephen Downes on Community

OK, so you want to do away with the hubs - "kill the spike", in your words. Let's take a look at another system that has hubs & spokes - airports.

Airlines learned years ago that the best (most efficient & economical for the system as a whole) way to move people in airplanes was to bring them to a hub, send them from one hub to another hub, then send them from that hub to their destination.

Now you're proposing we do away with hubs in our social networks, because it gets in the way of learning & community (or something like that - the why isn't really important here, only the how). There's two ways you can do that - make every node a hub & connect everybody to everybody, or only allow people to connect with their neighbors.

In airport terms, the first method means you need to offer direct daily flights from Altoona PA to Phoenix AZ (or have charter planes standing by in case someone has to fly that route). That means you need an awful lot more planes than we currently have, and they'll each carry a lot less passengers on average. In social network terms, evrybody has to keep track of many more connections & relationships than they do now, running up against & well past Dunbar's number. I don't think this is the system you envision, but I include it for completeness.

The second way to eliminate airport hubs is to outlaw flights except to the nearest arports. So to get from La Guardia to Boston Logan you'd have to catch a connection in Providence, RI. Imagine a trip to LA! No thanks. For social networks, you have the added problem that what's being passed is information, which in a social setting tends to be lossy - remember playing "whisper down the lane"?

In both systems (all-all & neighbor-only) you're creating an inefficiency to the system as a whole. There's a reason scale-free networks arise spontaneously in so many places - they're energy-efficient, by definition they scale well & they're resilient against most real-world disaster situations. Against all that, I just don't see the advantage of your ideas.

Tim

Stephen Downes on Community

Just curious, is it -all- scale-free social networks you're against, or only -some- of them? If it's all of them, how do you propose we deal with the scale-free networks that appear in (for instance) mailing lists, instant messages, wikis & the open source software developer network? If it's only some of them, what's your differentiation criteria between a good scale-free social network & a bad one? I'm trying to get a handle on how radical & far-reaching your plans are.

Tim

Stephen Downes on Community

This question is a bit like asking me whether I'm against all sine waves or just the ones used to carry radio signals.

And, of course, I'm not against sine eaves per se, but I am arguing that unless they are modulated, we get nothing but noise.

My proposal is essentially the proposal that we should modulate networks in the way that we modulate sine waves, so that the resulting signal contains information about the content of that network.

So if we look at other sorts of networks, we ask: are they intended to convey meaning, and hence 9say) create community? Do they do it effectively? Could they be improved? Each of these networks is different.

Email: the big spike phenomenon in email is similar to spam. Mailing lists represent a clustering of email, and is an improvement. Mailing lists dominated by one or a few people are not as good as mailing lists with more participation. Recent work in online discussions (see, eg., Collins and Berge) address increasing participation.

Instant messages: networks are composed of relations among people (similar to social networks). The power law in IM is pretty flat (few people would have more than, say, 100 'buddies'). Spike phenomena in instant messaging correspond to spimming (IM spam).

Wikis: recent proposals in the world of wikis have aimed toward increasing the big spike by 'embracing elitism', that is, reducing the impact of long tail contributions. For reasons well documented elsewhere, I would oppose this trend.

OSDN: I don't know enough about its internal structure to comment meaningfully.
