I use just about most every major social media site. I use pinterest, instagram, wanelo, bestie, twitter, wordpress, facebook, stumbleupon, ect. I have found that sites like wanelo, pinterest and instagram are really good for getting views because they are picture based. Facebook is good to because I can interact with people and share pictures of my items. Twitter is good for the same reasons as facebook and plus I participate in Twitter parties.
