I like Dribbble and still find it useful, ultimately I use it for what it's made for, to show what Im currently working on. I use projects a lot to show the progress of what I'm working on and it's cool to see how projects evolve over time.

I have no problem publishing unpolished work on there.

I must admit however, it did my head in when dribbble went through its 'animated hamburger' icon phase.
