Good idea, Im on there too... http://dribbble.com/davewi11
Ive been quite active lately and made loads of new connections, up until a month ago I hardly used it at all but I do find it useful to get feedback on snippets of my work.
I am also on dribbble! I usually use it for inspiration and I found it really motivating for me because there are some many great designers there.
Here is mine, I am only a prospect as of right now so none of my work is up there but I love following other great artists! http://dribbble.com/StevenAnthony
Some of you might have already seen my post about being on Dribble, but since I was just informed that a thread had already existed I'll post it again here! http://dribbble.com/HuemorDesigns
We have a pretty good number of work up there now and would love to hear what you guys think.
