The Curmudgeonly Clerk discusses anonymity of sites here. I agree wholeheartedly with his conclusions.

I could not talk about my students and my work if you knew who I was. I couldn’t discuss my life with any strength.

There are some people, perhaps even reading my blog, who know who I am, but I do not think that it is traceable on the net. I could be wrong. If you are good at that kind of thing, please see if you can tell me who I am.
