Jill, have your sites suffered significantly?
Some home pages have suffered. The more competitive phrases. For a few days, inner pages of my client's sites were showing up, where once home pages were, and the results overall appeared more relevant than they had at first.
Now, the results are looking much less relevant again, and more home pages are MIA.
I'm sure they're still tuning the dial, so to speak. Right up until they think they have the relevancy issues fixed. It can't be a great thing to only show pages that only peripherally have anything to do with the search query. They might as well be AltaVista or Excite or whatever if they're gonna stick with that. I'm sure they don't want that!
