BEFORE MY THOUGHTS ARE SCRUTINIZED BY MY PURPOSEFUL TENDENCIES.
I think that forum images are somewhat of a waste of resources, the link to "us" that a picture entails is entirely illusionary, much like knowing the faces of powerful political leaders has little relation to their abilities or philosophies.
A name (like anonymous14z) sufficed as "visual information" that gives us our identity and any more (a picture) is merely auxiliary information that answers the questions "how can I make myself more easily identified" or "how can I make myself seem like a better person", answers I feel are silly waste of time to find (unless if I want to be a newscaster or a politician).
If my privilege to have a forum avatar were revoked, I would not be terribly upset or inhibited.
Also, I'm really digging this video game music http://download.kdlab.com/music/Harkbackhood_Psychosphere.mp3
