I'm seeing what johnhh is talking about, only sometimes it's backwards. And I've talked to other users who are seeing it, too.
The way I've seen it "backwards" is like this: I can rank for "widget thing" but not "widget thing tutorial." The more specific keyphrase may bring less, but more focused, traffic. Whatever Google is trying to do, I think we need to understand it better, and if even three or four of us are seeing it, maybe it does merit its own thread so we can really get into it.
