i'm up there, have been for a while now.
can be found here:
http://dancarter.deviantart.com/at its core, deviant is a great idea. it's a good community and i've gotten to know a few really nice, constructive people that comment and point out errors and are just generally friendly-like. i've also gotten a number of illustration and design jobs from their forums.
that said, there are some things that are problems....mostly are the same sort the majority of internet communities have. trolls, flame wars...etc. certain forums must be tread into very carefully or you're liable to get really, really mad at some point down the line.
still, when you think about how much art is getting out there for anyone to see, that's an amazing thing. considering this fact and the pros listed above, it's a great launching point and a really good tool for anyone trying to break into the field or just exchange ideas about art.
