i would have written "silly_little_noob" as a name for the purpose of this thread. lol.
Personally, I consider people who post names are those who wish to have direct conversations regarding what they posted. Kinda like writing a "from" address on an envelope for the sake of encouraging your recipient to reply. Thread-wise, I'd use it so that a reply to a post may be addressed to me directly if I consider my post personal enough.
Otherwise, I like it anonymous to encourage a more "everyone say anything about it to anyone" kinda feel.
