The only time I've posted anonymously I called myself Guest - Temporarily Anonymous, and it was for a specific reason which involved my not using my "handle" for that particular thread. I have never logged out just to post as a Guest to a thread - the temporarily Anonymous one was a thread I had started to ask about issues relating to the identity in reality of an online person. Do people really log out and then post opinions to threads as if they were mere guests? Why bother? It's not like anybody knows who you are in real life who would change their opinion of you, and anybody who already knows you in real life won't change their opinion of you anyway...
