The second Tweetup was at a favourite gelateria: an opportunity to meet local & active social media people. Tony the organiser (@hollingsworth) had set up the tag #gelatotub and used Eventbrite to collect responses (no cost for free events and excellent for managing paid ones).
More good connections: Rebecca who I knew as a chef 15 years ago and has 22,000 twitter followers for her food tweets!! Mei, who manages community relations for the famous Brasserie Bread, retail guru Nancy and a host of others. I added some theatre with a laptop running VisibleTweets up on a shelf - it shows a continuous, colourful display of your chosen tweet word or #hashtag. It didn't take long for iPhones and Flips to record videos and pics - Posterous seems to be the preferred way to share them eg Tony's collection.
If Twitter makes sense to you, track down or create a Tweetup and expand your network of like-minded people. Even searching Eventbrite for your location will reveal some surprises. Oh, and I'm on Twitter at KenBurgin.
