I have been known by many names too, some not so nice, my better half calls me sweet cheeks, but it'll be a cold day in Hades before I post as such.
I have to agree with Vance that in many cases people who use a false name are more apt to misbehave and speak ill of others, after all, they can just be someone else the next time. I read an article somewhere once about people using false names and avatars on-line and why, something about fantasy and living an alter-ego, it made it easier for them to slip into a persona that they projected on-line...something like that anyhow.
Each has the right to do as they feel is needed, as for myself, I'll use my real name in conversation, forums, articles, etc. If you don't agree with me, then it is Will Heath you disagree with, if you do, then it's still Will Heath, and when we meet and you look me in the eye, I'll say, I'm Will Heath, please to meet you.
I speak from experience, I used to post under the name of BadByte, a name that I used way back before the Internet existed as we know it, just bulletin boards, no pictures, and flaming wasn't heard of yet and hacking wasn't defacing web pages.
