A question for Twitter-heads

OK, so I get the premise of Twitter, but at the same time I don't. While I don't have many important things to do, I know that I do have more important things to do than to subscribe to a Twitter feed. I don't have a Blackberry or a phone w/ Web capabilities. I check the news when I need to: Every few hours I'll check out the Chicago Tribune, Lawrence Journal-World or Kansas City Star to learn what I need to. I see Yahoo's homepage every half hour or so. So, Twitter, what up? What's your deal?

Furthermore, per Mindy McAdams' post about the future newshound, does Twitter provide location-specific feeds? Say I live in Kansas City, Mo., or Lawrence, Kan., or the boondocks of Nova Scotia, can I find feeds from my area? I'm curious. Sell me on Twitter. I dare you.
