> so the like button no longer works as an upvote system. I don't think it ever worked as an upvote system. I think that many users have that expectation, but Facebook has never really used "likes" alone to determine news feed placement. But I agree, I think this social phenomenon combined with ad blockers (which effectively block Facebook's data feed into what sites users visit outside of Facebook) will lead to significant downward revenue pressure on Facebook. There's not really anything competitive yet; but advertising doesn't feel like a viable model long-term.
