I have a hard time relating to your question. I make a point to sign my real name to anything I write. If I felt I had to adopt a disguise in order to kick in my two cents around here, I'd probably leave. For me, living an honest open life is much too important to use pseudonyms.
I can understand that many folks don't want to use their real "parent given" name on the internet out of concern for safety and security. But to slip on various characters in order to be clever just doesn't make much sense to me.
I'm just sayin' is all.
