Popular blog host Blogspot is blocked again in China (see this Danwei post for chronology of Blogspot’s availability in China).
On the other hand, Google Video seems to be working in China for the first time ever since it’s launch. So you can, for example, watch this discussion from 2006 hosted by James Goodale with Rebecca MacKinnon and Timothy Wu titled: Did Google Sell Out in China?
Update: The embedding function still does not work in China. As readers have pointed out by email, Google Video’s availability may be a result of Google policies, not the Net Nanny’s interference.
