Thanks for the link, chuckcode. Skimmed a bit and added to the "read before bedtime" pile.

There's a lot of interestingness around anonymity vs. pseudonymity. From what I've read and experienced, it comes down to how much you value a particular identity in a particular context; from there, it's all about framing incentives around the identity that you value. Violentcranz didn't value the online persona enough that online incentives mattered; when he was outed by a journalist, he valued the real life incentives enough to stop the online behavior.
