Here's another thought I'm having about the changes in one word search results .Perhaps Google is making heavy changes here to accommodate Universal Search.

In order to display videos, etc, on the same SERP they did need to somehow normalize the relevance algorithms for regular SERPs with the legacy relevance scales for video search, etc -- and they may not have got it exactly right when Universal Search launched.

I'm thinking that one word searches might be an important place for them to get Universal Search right, and hence the big changes we see.
