@tedster: I agree finding & penalizing contents farms like ehow.com etc is something too hard for an automated algo.
I've actually been thinking about this quite a bit, and I'm thinking I'm going to (we all should) NoFollow back ... We're the ones giving these sites like ehow, wikipedia, etc. a large number of their links ... If their going to nofollow (or hide) links out, why shouldn't I (we all) NoFollow all links to them too?
