Pinterest was one of the most heavily trafficked social media networks of 2011, which was surprising to many because its rise to success was a quiet one. Pinterest is a form of social bookmarking where users pin different images and YouTube videos from across the web to boards they’ve created based on a subject area of their liking. For instance, you can create a board entitled Best Places on Earth and then pin images of island getaways, beautiful landscapes or whatever images you think fit this board best. Your boards are displayed on your profile for your network to see, like or repin to their own boards if they so choose. You’re able to follow other users and/or their individual boards of content they’ve assembled. Pinterest allows users to sign up through their Twitter or Facebook, which makes it easy to connect with your friends already on the network.
