Google brakes blogs?

Olivier has dropped from #2 to #7 in Google. He wonders: is Google braking blogs? Tony Pierce, once #1 for Tony, is now #11. I see Dave Winer has the same symptoms. David Weinberger notes that he has plummeted from #6 to #25, supplanted by namesakes like David Bowie, David Lynch, David Gray, David Brin, David Grisman, Harry and David.

Inspired, I just spent a couple of minutes looking for myself among the Henry clan. After 6 pages, I gave up. Note to self: create an app allowing bloggers to track their Google status.
