Hah! This is excellent and exactly what I see happening out in the real world. People don't like the unpleasantness and turmoil of disagreeable ideas and people with those ideas, and so the solution is not to burst the comfortable down-pillow bubble of their existence, but to pad it further by "eliminating" "negativity". Even better considering who gets to decide what constitutes "negativity". Fantastic job, guys. Bravo. Edit: There are some salient points here about downvoting and how it's affected the community, and I am extremely interested in how "to turn more moderation power over to the community" is going to compound the problem of incentivizing positive-only feedback, id est if and how this "community moderation" mechanism will couple with downvoting to make disagreeing even more hazardous.
