Well, I didn't pull my username out of a hat... Everything is already tied to my real name, and it's been impossible to separate the two from the get-go. Facebook requires a real name, Google+ requires a real name, and I've got my own website which is literally just my name .com. I've got a game development blog which uses my real name, and if I'm on a site like this where I may want to discuss something I've written or some project I'm working on, I might as well use my real name, since you'd know what it is anyway. The size of the site doesn't matter much, since I was /u/CraigEllsworth on Reddit, as well. Once upon a time, I used more anonymous usernames, and I guess on occasion I still do, but for the most part, I don't feel the need for separating the physical and the virtual anymore. I try not to do anything that I'd regret, and it usually works out.
