I notice that there are two types of posts that seem to get tons of likes on a forum.. Posts that are really on point, and troll posts. I've had a few posts recently that had 30-40 likes, but someone could easily grab just as many by being humorous or trolling, etc., and that's what's happened here historically.
The reason up/downvoting generally works on Reddit is because Reddit has a long-established culture of trying to promote the best replies -- but even Reddit has plenty of subs that fall prey to brigading, dogpiling (when people don't really try to understand a comment or fully read it, but just add to whatever the vote total is), etc. Reddit also has threaded commenting, so whole conversations generally stick together, etc.
Here, since the replies aren't threaded, the conversations become scrambled and out of order if you sort it, which becomes a bit confusing.
Based on this I'm not really sure how useful this'd be here. I'm not really in favor of using it for threads generally. Maybe if somebody asked a very specific question, but that's it.
