I was chatting with a few folks who are convinced of a major Google update. David Ogletree was the first I know to spot this. So I revisited a WebmasterWorld and sure enough, since the 18th of this month, four more pages about a possible Google update.
Now, I suspected something was lingering when I wrote about the Possible Google Valentines Day Update but Matt Cutts of Google knocked me down with his comment.
But this truly does appear to be a Presidents Day Google update.

A big drop in traffic over the weekend / last 2 days for me. Anyone else seeing this?
Followed by dozens of responses confirming this.

I don’t see this as a true rollback – some of the SERPs I monitor have a whole new configuration.
Based on this thread, I think this is the real deal.
