Millions of Markets of Dozens

I'm assuming that the BNoopy blog is by Joe Kraus, founder of JotSpot and previously Excite. The blog has no attribution whatsoever, but does use "Joe" once in the 3rd person.

Anyway, I just read a post a BNoopy called The long tail of software. Millions of Markets of Dozens and it really opened my eyes to what the "long tail" means to business.
