Avatars and profile pictures are for the insecure and weak of mind! I'd get rid of my dumb custom title too, if I could, but it won't parse with just a space. :< I only use avatars in the event that some awesome 64x64 icon just doesn't look right in a signature. That pretty black space under your name can sometimes be useful for aesthetic purposes.
It's a matter of preference, but I feel that any relevant info to you should be present in a signature. Avatars/profile pictures serve no real purpose other than to identify who is posting, and we all can (hopefully) read English so why not just read the poster's name? Anyways, as I said above, sometimes they do look pretty. Most of the time they look retarded, though; people have no sense of style these days.
