OK, this is too funny. I was just looking at Analytics data for the moved pages, and I realized that my search traffic has been rapidly falling - from Bing and Yahoo! (same thing).
For the highest traffic of the pages moved, Bing and Yahoo! used to account for around a third of the visitors. Last couple days they've been down around, ZERO.
So whatever happens with Google going forward, apparently Microsoft figures that moving pages is evil. Maybe I should sign up for their version of WebMaster Tools and see if it makes a difference.
