It's a bummer the coverage of the olympics continue to be controlled fairly tightly by the media. Like pb mentioned, it'd be really great if athletes had ways of sharing their experiences in real time on the web.
So far, I can only find two people tangentially related to the olympics, and running weblogs chronicling their day. Crabwalk is done by a journalist covering the event, and b-may is Bryan May's musings on working security at a ice rink. I met Bryan last year at Web2001, where he kept all us speakers happy and everything running smoothly at the conference. He's a funny guy in person and I always wondered if he'd start writing on the web. His site is absolutely hilarious, and captures his infectious sense of humor well.
