I do, because it is instantly verifiable to prospective employers who want to see things I've worked on. I don't think there is anything wrong with using a pseudonym in this case, but doing so would make it at least one step more difficult to verify that you actually wrote the code. Also, it keeps me more honest. If every commit has my real name attached, I am more likely to write clean code since I value my reputation.
