i don't think it can be tackled... it's all just math and those guys seem to be pretty good at it. It would be nice if everyone just manually curated and everyone could just be happy that way but it isn't gonna happen.

I don't mean to jump on the gravy train but i would like to see vast improvements to the User Interface and implementations of FB - esque features to assist in onboarding the masses. It's not for me, but for the general public, if that makes any sense.
