The flaw in HN/reddit votes, Twitter faves, FB likes, etc is that not all persons who see a submission will use them. Every silent observer contributes to that illusion of assent that helps entrench deviant behavior.
Timelines are great tools for skimming content, but while we can aggregate content easily enough ("scan the room"), we have no tech solution for returning the social feedback that meatspace society relies on ("the room fell silent"). You could force that feedback by turning the timeline into merely a historical lookup, and delivering new posts to the user individually and not letting them return to the rest of the app without interacting with it in some way. Also, block unregistered users entirely, unless they can be locked into the same use pattern by some means that escapes me at the moment.
(If we split off into sci-fi dystopia land, measure the user's emotional state as they scan each post and accumulate those scores back to the author. This is terrible, please no one ever implement it.)
