Depends on how rigorously one enforces their "Pyramid of Debate. That has its own set of mountain-like ranges to overcome vs. "reddit hordes' mentality" for 15 years of upvoting/downvoting being 1:1 agree/disagree, despite what the Official Rules over there say. Seriously, as noble a pursuit is as guiding and shaping the thought process behind communicating on an internet forum with an abstraction divided into "insightful:fun" (wtf even, "fun"... if that's the best you can come up with, it should point to the problem of your system already) to REPLACE an abstraction divided into up:down -votes with supposed meaningful thought put behind the decision to click one or the other... it's most probably going to be a failure.
