Pinterest is basically a site for 'pinning' (ie posting) photos, images, etc etc to certain 'boards' (I have one for funny stuff, one for lovey stuff, stuff that makes you think, hot men

)
It's kind of like facebook, but it's just images
Pinterest / Home is the website

it IS really addictive, I joined on a whim, and now whenever I'm online and see a picture I can't help but think "oooo I have to pin that!"
Oh & Amelia, I am on Pinterest, I think we're following each other anyway? I log in with my FB acct
