Social Media Experiment: Create an ongoing event and only promote it via Facebook/Twitter/social networks. In-person networking groups and bars are combining to develop what is affectionately called a TweetCrawl, half happy hour and half networking, where people are brought together in local restaurants across their state. Live tweet rolls are shown on large screens where compatible contacts can see who is doing what and know who to tweet back to for a business connection.
