Pinterest

Pinterest has been taking off as of late. The idea is simple: As you browse the Net, you can clip images that you like to a digital cork board that you can share with other Pinterest users. I hear you asking: Isn't that what Tumblr's for? Yeah, sort of, but Pinterest takes the blogging aspect out of the equation and focuses on making it easy for you to share your images.

When combined with your Facebook, Pinterest will turn a section of your Timline into a cork board that displays any and all cool images you ran across while browsing the Web. If your friends dig it, they can leave comments and pin their own photos. Just make sure they're SFW. You know your Mom is peeping your profile.
