Although I like many bookmarking sites, I must say I really like Pinterest. I can not believe I just opened an account with them. Pinterest has it were you can pin and share photos in minutes. Many demographics will use this site: artists, students, and business professionals, just to name a few. I also think it is good for promoting a business because is also connected with Twitter and Facebook, so when you take a picture of the product you made or sell you can share it with your followers, or publicize your photo and share it with anyone.
