Yep. If it hadn't been for this forum at WW, I wouldn't have been aware of it.
As far as I can see, nothing has changed except some wonky backlink stuff, which comes and goes. Using Firefox on .com I only get the bizzaro link:www.example.org occasionally, and then they'll go away if you clickrepeat the search with the omitted results included.
Call this update the bizzaro backlink update, because that's all it is.
