As Darren would say, this is a boring site note. I have finally turned on Captcha for comments to blog posts. This means that, in order to post a comment, you'll have to answer a simple question to prove you are human. I have a feeling you'll pass the test with flying colors.
More than anything, I want to know if you have any problems with the system. Thanks.
Updated: I'm testing a new system that I can't discuss right now (it's in private beta). This means that you may not see the captcha question as described above.
