As far as I can tell, the fun of Twitter is not in tweeting myself or in following people I know personally, but instead in following public figures -- celebrities, journalists, athletes, politicians, musicians. Here's what one gets from Stephen Colbert, for example:

I'm also enjoying Ezra Klein, Andy Roddick and Rob Dyrdek. Andy's life consists of four things: "going to the track," "practice," "eating!!!!!" and "watching the BB game". Dyrdek occasionally shares pics of his two bulldogs and seems to have a staff dedicated to finding funny youtube videos for him to share on Twitter. You could use it less for entertainment and more for utility: local businesses, theaters, restaurants, community organizations, non-profits, etc Twitter too.
