Hey there, I don't link out so that can't be it. I have a theory what is going on, it could be that google is reevaluating the website as a whole, completely recalculating all incoming links as it sets up the next visible PR toolbar update for October, and meanwhile I'm not in google beyond what I used to be (I'm ranked for keywords just about as well as I was during the last PR update, they must be using the same ratings for me that existed then while they're recalculating). That's my guess anyways.
