I read the explanation of this update that Google provided and the impression I got was that it is measuring sites based on trust and authority more, and it also doesn't trust user-generated content as much as it used to. I mean, look how they added the rel="ugc" specification to specifically look at UGC. This means things like forums and wikis and similar web 2.0 style platforms where users get to post stuff on your site have lost some ranking because in Google's eyes, they're a type of "content farm."
