I don't think it will work in practice. Reddit and other voting platforms require a login to prevent spam voting and do people want Google to know which articles you like and don't? Reddit works because anonymity which Google will not provide.

But Reddit, along with most major sites now, is also rife with the same marketing manipulators and "influencers" the article is commenting on. Digg tried something similar before Reddit and was pretty much ruined by biased organized vote manipulation (brigading). Not that I agree with Google's "trust us plebes we know better than you" model of secrecy either. The SEO problem is the prime example of why this doesn't work also. Search engines have become a vital resource for the modern internet. We need an open, publicly funded non-profit search engine.
