A review of threads on 2.0 shows there isn't much specific information on what's happening with this update. I see general threads about building more high quality links, blah blah blah. It's imperative that we share information on what just happened for those (including me) that are kind of in the dark about it. I was fairly confident in my extensive natural keyword profiles. Seems like there's other things at play here. Try to keep the thread about objective information. Not complaints that google fucked you.
