I just read that Pinterest is now the third most popular Social Media site is the worls behind Facebook and Twitter. I've got a Pinterest account but have never used it. The top demographic is female hobbyists. I haven't caught any buzz about Pinterest being used for business. Are you a Pinterest user? If so, how do you use it? Just for fun, or for business, or both. Have you got any tips you'd like to share? Please post your thoughts.
