Plurals and in general semantic search no longer works. It used to, but now all keyphrases have been "priced" and the new rule seems to prevent too much related search, which would be good for the user, but short change Google. In the end it's all about Google.
Yesterday Thursday 8/30 saw a huge (negative) change in position and traffic. The only changes I'm making to my site are structural, updating some old html pages to css. Seems like right after I published some new "cleaner" css pages (and their associated dwt template) the traffic valve was shut off. Might be a coincidence, but it might also be a result of that "make a change and you're labeled a spammer" patent. Google is fostering more paranoia than love these days.
Seems many others are seeing a similar downward shift again, so it's probably just another iteration of Penguin. Let us know when the tweet comes in to confirm. The 1% wants to know.
AS far as Bing, In recent days, I am also noticing their serps looking more like Google. I removed all keyword meta tags a few weeks ago, so maybe that's it for my niche. Looks like some search engines may still use them.
