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.
> I try not to do anything that I'd regret, and it usually works out. Isn't this the real take-away. If you have a username that you feel is totally anonymous you might post different, or at least not give each post the same scrutiny as you do now. Do you think that you consider what you post more carefully with your username linked to your real name? Being anonymous on the internet can mean leaving some of the polite bits of you behind the keyboard. On the other hand, who knows what people take offense to, and as careful as you are other people are still free to act in a way that would be unacceptable irl.
