Twitter (and other social media) tales

I’m looking for stories. Good, juicy, social media marketing stories. Are you a marketer that has a terrific story about a social media campaign that saw some serious success? No matter what size business you have, and whether it’s a tale of Twitter, Facebook, MySpace, blogs or anything else, if it’s a story that will help your marketing peers learn from your success, please pass it along to [email protected].
