I first tried using my real name back when blogging started (around the same time as Journaling file system buzz on Linux). It was difficult to switch gears from attention seeking.

I "lurk more" when using my real name since I try to use communities where other people are more insightful than me.

Also I noticed a common pattern of "20 questions" when I was using aliases about innocuous Questions Answered Frequently that over time eroded my confidence in my anonymity. e.g. vim versus emacs is one of the 20.
