You have to get in, use it, and add some people to follow before the hook gets set. There are third party clients which display public messages on a timed basis, for instance, which greatly enhance the experience. "Twitterrific" for OSX is a great example.
Most of the Tech TV/podcasting crew are on it, and a lot of the links they post are really useful/interesting. Even Henry Rollins is on it, but he hasn't posted in a couple weeks.
But what if I don't want to know what you are doing every 5 minutes?

Then watch the public feed of people far more interesting than me.

What I want to know is, has anyone put out a sidebar Twitter app for Vista yet?
Try this...
First thing I found doing a google on "Twitter gadget".
Dunno how it its. Probably others out there as well.
What I like about it is that a lot of people put up links, so it becomes more of a "Digg" experience when you watch the public feed scroll by. Every page refresh delivers 3-4 links that I haven't seen before.
