Certainly the best explained "defense of anonymous blogging" I've seen. I was challenged this week by an anonymous commentator on my blog to reveal myself. How crazy is that.
You can see my comments in detail at this link, so I don't cut and paste here.

Anonymity has tremendous value for the bloggosphere.
Thanks for saying it soooo well.
