Since we've lost at least half our traffic across 8 sites (and in one case about 90% of traffic), and since I have no idea what google is doing, or how to address it, we're simply moving off of the Internet business until such time as things get stable, and predictable.
All this based on 30-60 days of unpredictable Google behavior? That might be a bit of a knee-jerk reaction to something that is probably going to correct itself in time, hopefully. I know, it's that "hopefully" part that most are concerned about. But, usually 8 out of 10 times things clear themselves up "naturally".
