Warning: anonymous comments

Just because I have just run into a person who did not know this bit of trivia:

When you post comments anonymously, they are anonymous to the outside world. They are not, of course, anonymous to me. I usually know who you are. So if you (especially somebody who knows me in person) are commenting anonymously just in order to avoid discussing the matter with me, don't bother.

Of course there are ways in which you can hide your identity, but is it worth the trouble?
