So what's the fuss about? Glad you asked. Twitter is mostly about communicating with a lot of people (friends, family, colleagues, etc.) in an instantaneous and informal fashion. Business has always been about relationships first and foremost. We all know that we are more likely to do business with people we know and like. So for me, Twitter (as with Facebook which I mentioned last week) is about building and maintaining relationships with many people at once.
There are people on Twitter who have over 20,000 followers (that's right twenty thousand). That means that when these people rant or rave about what they see around them, 20,000 people hear about it within seconds. That's pretty powerful stuff.
I think Twitter and like services really are going to change the world as we know it. I think Twitter will become as ubiquitous as the telephone. If you don't have an account on Twitter, you'll be considered a hermit. Lest you be considered a hermit, you can create a Twitter account here: http://twitter.com
