What is twitter? Twitter is a service for people to connect using short, 140 character messages. Sending a twitter message (a “tweet”) can be done from the web, a twitter desktop application, or through a mobile phone. I’m tweeting from my iPhone a couple times a day. If you’re a trusted friend, you’ll get all my tweets. Other people will get public messages, and notes about cool and interesting tools, gadgets, and products I see throughout the day. Join twitter. You follow me, I’ll follow you. It’s like talking, without all the awkward silences.
