>> And what is "this type of criticism"?

Perhaps gross generalisation is a fitting term? Basically it's somewhat insulting to insinuate that designers on Dribbble believe glamour shots are the be-all and end-all of design. I've heard several prominent Dribbblers interviewed on various web design podcasts, they know what it is and what it isn't.

>> To me it looks like the design world...

Whoah there, you can judge the collective opinion of 'the design world' from your desk?! :)
