Any picture is better than none. But something that describes you, wether it's your personality or outlook. Maybe a couple of graphical suggestions would help us decide?
I always find it interesting when people put themselves in their Avatar - nice to have a clue what a person looks like. But then I have this insatiable curiousity....
Speaking of. How did you get an avatar that's larger than the size limits? I had to spend quite some time trimming, cropping and resizing to get it under 80x80 and still be recognizable.
I prefer it when people have a picture of themselves. I would have one, but I don't have any pictures less than about 3 years old, right about the time I was hitting puberty, so I'm not too pround of those. Have to get some more pictures.
