Two blogs I'm following that give deep insight into the Chinese Olympics mania:
Vincent LaForet is a Newsweek photographer blogging on the subject of covering the Olympics from his vantage as a world class sports photographer. He is sincere, modest, and revealing, and I'm so glad I don't have his job.
James Fallows is the pre-eminent Atlantic correspondent, who is writing about the Chinese Olympics as an expat observer. An erudite viewpoint you won't get anywhere else.
