Here is an interesting story in the NY Times about Apolo Anton Ohno. I have to admit that, going into these Olympics, I did not have the highest opinion of him (Dancing with the Stars,really?). But I have been impressed watching him, and this article is really instructive about who he has become over a long time.
Shaun White was another one of those "famous" athletes that I did not focus on very much prior to Vancouver. His performance in the half-pipe, however, was simply amazing. It was great having the reference of all his other competitors, so you could really see how much better he is.
Pretty enjoyable Olympics so far - with lots of hockey to come! And the hi-def broadcasts show what hi-def television was meant to be used for. I am particularly amazed by the ultra-sharp slow motion replays.
