About 38 minutes in, the session morphed into a general Q&A. So even if you don’t care about site reviews, the Q&A might be interesting to you. Video aren’t perfect (for example, it’s much harder for someone watching a video to skim quickly). But I love that I can do a two-minute video by just talking for two minutes. Compare that to any blog post which seems to take me at least an hour.
P.S. If you like this session, you might be interested to know that most Google I/O sessions were recorded and are available on video. For example, one of my favorite sessions was watching Aaron Boodman (author of Greasemonkey) talk about how to write extensions for Chrome. The amount of information available from the full session list is pretty amazing. That’s not even counting the Google Wave announcement, which has been viewed about 2.5 million times.
