How To Find Out Who You Are

Sometimes I would really like to know the identity of the folks commenting on my blog entries. But java.net just gives me an email address of "foo@bar.com" and a java.net userid, which for the life of me I can't figure out how to dereference to an actual person.

I'd like to see your blogs, see what you're working on, what company you work for, what you're talking about. I can't do any of that.

If anyone has any tips, I would greatly appreciate it.
