On the other hand, I use my real full name here and most everywhere else. I agree that explicitly rejecting anonymity is a solution, but strongly disagree that it would work for everyone or should be forced on anyone.

I agree it wouldn't work for everyone but I actually find using True Names a good filter for my own actions. When I write something, it forces me to ask whether I'm OK with people associating it with real me. And if I'm not, with fairly rare exceptions, that's probably because it's something mean, snarky, or offensive that probably doesn't really improve the Internet in any way.
