"What has Google changed that has led to higher rankings for megasites?"
It would seem to me that that google is relying less and less on it's ability to understand semantics and language in its algo, and is relying more and more on other factors.
It seems strange because, really, google's ability to understand language and semantics seems like its ace in the hole. It is a core competency that no other organization seems even remotely capable of matching.
Other factors - such as link profiles, social activity, and even user behavior - can be exploited to a certain extent by google's competitors. For instance, firefox and opera could probably sell user behavior to bing and other search engines, and I am guessing that MS could just provide user behavior from IE to bing.
so to me, it just seems weird that google would marginalize its key competitive advantage in its ranking algo...
