pinterest elitist assholes!

So I see people's really cool blogs and I think "Pinterest, what's that?  I like that website!" and then I see that you can only get an account and post the things your are (P)interested in if you are invited.  They send you an email about being on a "Waiting list" after you request admission.  As if there is a capacity sign hanging over the door to the freaking internet!!  Right.  I just want one...Can you tell?
