IMO in today's community (too big and less and less acculturated in any sense than the past) we need personal websites that collect peoples public ideas and a discussion platform like usenet. On usenet there is a continuous stream of contents, valuable one may then end-up in some personal sites and being cited in future posts so newcomers can still discover it when needed/desired while not much valuable one slowly or quickly be forgotten in ngs history's...
Gamification while have some "attraction" for many does not really guarantee that valuable contents remain available and tend to push far more extreme/non valuable contents fading into oblivion most interest stuff that might be "elitist" by nature... This, of course, while NOT counting all possible abuse in both "artificial downvote" and pushing extra contents to "censor by oblivion" unwanted contents.
Splitting platforms like StackExchange or HN vs Facebook might help and might reduce abuses but IMO it's certainly not an answer...
