I really like the simplicity of you app. I have not been "blessed" with a dribbble account either, but I do have forrst and lovedsgn accounts. The problem is, I always end up posting pretty much the same stuff to both accounts, and I find that the people that frequent both sites are pretty much the same, and dribbble as well. I wonder if there is something you can do to differentiate it from "the big three". Perhaps a rating/feedback system that's different than "likes" to captivate useres?
I really like what you have going, I'm just offering my 2 cents :)
