@Keynup: I believe people downrate for off-site features because some people (myself included) prefer staying on the same site as much as possible. In general, I find Kongregate to have a better design than a lot of other sites, and dislike feeling that I'm being pressured to go to another site to get the "real" game. Typically I won't downrate if it's a few features that I don't feel are essential, but if they're substantial or powerful that merits a downrate from me. Facebook integration in the actual game itself, of course, is an automatic 1/5 from me, on principle; if I wanted Facebook crap, I'd be on Facebook, not Kongregate.
