What is the big deal over Pinterest? I'm not signed up and don't use it, but I understand that it's a way to organize and keep things you find online like photos or recipes....but isn't that what bookmarking a site is for? What's so hard about saving the link to whatever it is you want to save and putting it into your browser favorites?
Or is it more of a way to "express yourself" to others, a "look at me and all the cool things I have pinned" deal?
