TWEETMART

Tweetmart.com (www.tweetmart.com), started in January, is a Twitter classified service. Users "list an item online," and Tweetmart sends tweets to all your friends (we tweeted Tweetmart to find out whether "friends" means followers, followees, or both, but haven't been retweeted). Items remain active for seven days. "Post a job" lists jobs for thirty days. Users can resend posts at will.-Stuart Whitaker
