First there was sewing at home, then there was window shopping, now there is Pinterest. Pinterest is a brand new kind of social network where Pinners can post photos from around the web on their specialized virtual bulletin boards and share their findings with their friends and strangers. The beautiful layout features a never ending scroll bar which maximizes the chance of people wasting hours on the site without even noticing the time flying by. Pinterest is now a main generator of traffic to blogs, retail websites, funny Memes, and much more.
