I read, "With Twitter you set up a public or a private page where you post a line to say what you are doing, either from your PC (browser or IM), or by SMS text message from your phone. You can view all public messages, or watch someone’s site in particular. You can watch a friend or colleague and even get their posts sent by SMS to your phone. It’s a kind of gossip and instant consciousness oriented mini blog. " That sounds interesting and this could evolve into a social phenomenom.
