With over 10 million users, Pinterest has rocketed to pop-culture fame since its launch in beta in March 2010. This rapid growth makes it the fastest growing social media site of the past year. If you’re familiar with Pinterest, it’s easy to understand why. The system of “curating” all things found on the Internet is easy to use, free, and frankly, addicting. It’s a whole new way to collect and organize all those appealing, intriguing and interesting images and ideas you come across on the Internet every day. What’s more, you can share your boards with other Pinterest users.
