The Bar Is Open and Twitter is Buying

Here's a creative use of Twitter during recessive and competitive times: Clubs are sending tweets to followers with access codes to relay to the doorman to bypass the line and get in free, and others to signal the bartender for free or discounted drinks. A great way to drive traffic offline by using online promotion.

Zappos is known to do this to invite people to parties and even impromptu events wherever Tony travels. Follow him and drink up.
