Pinterest is a site for collecting cool things you've found online and sharing it with friends. It is similar to Tumblr, but it allows you to organize the things you like into sections or boards. There is a feed from your follows, feeds for all the different categories, and a feed from the most popular from all users of Pinterest. Anything can be pinned - categories range from home or weddings to food and fashion. You can personalize your boards to be anything you want, and they're always there to look at later. With the amount of everything on the site, it is incredibly organized, and that's probably my favorite thing about it. And of course, it has a ton of great ideas and is a lot of fun.
