MuHaHaHa!
I like Chris's anime avatar as well and Saber-tooth's tiger (he's gone now right?) too.
The theory is that if we all had avatar/logos, they would become too noisy in the replies. I'd like to test that theory out though. The only places I've seen it implemented is in the sites that use standard Bulletin Board software and it's just not pretty.
It would be a quick way to filter some of the random comments out and look for the replies with substance. Not that I'm trying to pay you a compliment or anything rdb!
Perhaps you're looking for something the opposite of the killfile, to make select user's comments stand out from the rest.
Of course not! I ain't nobody. Just a dude with a broken body and a broken brain.
Not that there's anything wrong with that. </Seinfeld>
