Thanks for posting this! My traffix starting increasing yesterday and your post here is the first notice of datacenter updates that I have seen. My pages are moving back to their pre "Allegra" rankings. Hopefully this latest update sticks :-)

Maybe some of the "fresh" sites, and sites just out of the sandbox, are starting to drop in ranking and the older "established" sites are coming back?

I swear sometimes when Google makes these huge changes my first thought is to make drastic changes. Usually though if I just hang in there and focus on creating good content and intelligent linking, Google will eventually come back around.

Respectfully,
