In a few weeks I'll be participating in a panel about social media, and I'm looking for examples of ways you or other entities have used social media -- from Tripatini to Twitter, from Facebook to Foursquare -- to solidify a brand's identity, to gain customers, retain client loyalty, etc. I'm grateful for any examples you can give me, and in my comments on the panel I can use real names or not, as you wish.  If you want to email me privately about this, send your comments to Ed@Tripatini.com.  Thanks.
