We noticed it here a few days ago. Then a few of our colleagues noticed it. Today, a whole bunch of the SEO and SEM forums are discussing it.
There appears to be, at least for for now (in specific spaces), a huge realignment in Google's organic SERP's (Search Engine Relaltive Positions).
Well, in the case where some companies have come to rely on their positions to maintain their staff and salaries, I suppose that panic is a more-than-a-little warranted. SEO's as well are concerned about client contracts, etc.
The important thing to realize is that every time Google makes a change to their algorithm, stuff is going to happen. The more feedback we provide the better!
Is this a repeat of the 'Florida mistake' a few years ago? At first blush, on some of the terms we looked at this morning, you could come to that conclusion.
The important thing to realize is that Google has more servers than ever before and until all of this gets 'washed out' and proliferates the servers, nobody really knows .... yet.
All we can do is hope that the 'new' results are more relevant than in the past, and if not, it is straightened out quickly.
