I love Pinterest. it's a completely visual social networking tool where people post photos that they've taken or that link to other websites. But to me the links and comments aren't important. I like to jump on, browse the photos, and like / reshare (called repin) cool pictures, and jump out. This usually takes around 5 minutes or so. The elegant web design arranges everything is a grid and is very easy on the eyes.
Pinterest also allows you to follow only certain categories, called boards, that a user creates. So if someone is posting about ugly shirts, I can unfollow just that category and still have access to the other pictures from the user.
Then my man Pierre showed up. He began following me and I fell in love with his old school tech pics. The I went to his profile page and saw that it's completely in another language! If this was another network, the language barrier would have effectively prohibited us from easily connecting on the site.
Pinterest is not the first site to offer this visual view. Instagram comes to mind, but it's limited to iOS devices and the site design isn't nearly as good. And Flickr is a little dated and more suited to serious photography.
