Penny Arcade addresses the entire ‘post under your own name’ controversy involving Blizzard right now. I think that it’s a fair take on both sides. Switching over to politics for a second: both MoeLane.com and RedState.com are pretty much against anonymous posters; you can post under a handle, but we require email addresses at both places for a reason, and that reason is mostly because it cuts down on the trolls. So there’s that. On the other hand, if I did my political blogging under a pseudonym I wouldn’t have sabotaged whatever hope I once had of getting work in the roleplaying game industry.
