How embarrassing. On the other hand, the only clue that he's one of the authors of dojo is that he links to dojo projects in the sidebar a lot, but he also links to chromium and webkit. Should I assume he's one of the authors of those too? (He could be, I've no idea)

Yes, he's the principle developer of Google Chrome Frame and works on the Chrome team at Google.

His most recent post is worth reading, as it expands on his position: http://infrequently.org/2010/10/story-time/
