Of course. Based on my opinion, I like the clean look and great organization of dribbble as it is mainly for graphics. I’m more of a visual person so art and design is more of a trigger for me than looking at code. I also like the fact that the site isn’t swarmed by less than interesting art and that your shots are seen by everyone. So having no privacy to your shots clearly makes it challenging to not submit something less than par. I also enjoy the hard to come by invitations.
I can understand all of those points. I also enjoy the exclusivity of Forrst, and agree with the lack of privacy acting as a safeguard against posts that might be considered below par. Dribbble looks like it is more aimed towards designers?
