So there appears to be a google shuffle going on. I looks like more than the normal everflux that Matt loves to talk about.
Here is great piece - the comments are pretty interesting from Aaron's SEO Book Blog:

Also alot of chatter on WMW:
http://www.webmasterworld.com/google/3261715.htm is just one example.
I can't really tell of many patterns with Google it is so hard to tell. But the usual advice still holds true - links, links, links, links, quality link and a sprinkle of good content.
Actually have great content or service so you don't depend on the search engines is the best way to go.
