I think that most trilogy users, as concerned citizens, will downvote or at least comment on wrong or misleading answers. That part of the system works.
However, very few people seem willing to downvote questions. As I mentioned in another comment, at the time of writing, there is not one single downvoted question on the front page, but at least 3 questions with moderate views, vague/useless titles and unclear content.
It's not hard to see why question downvotes are so rare. Consider the following:
Downvotes cost (a small amount of) reputation;
Question downvotes don't directly benefit anyone; they look and feel mean-spirited, even though they do benefit the community as a whole by enforcing quality standards.
Cretinous random/pity upvotes prevent all but the worst questions from staying below 0;
Various badges reward mass voting (which, taking the above into account, always translates into mass upvoting.
Overall, in the long haul, I think the system cheapens upvotes and reputation, because they become so easy to gain by asking a lot of poor/mediocre questions. This problem has been partially fixed by lowering the rep gain from question upvotes, but that's only half the equation; without at least some downvotes to balance out those upvotes, we're only delaying the inevitable.
So here is my totally insane suggestion:
Split up the Electorate badge.
People want balance between upvote and downvote incentives. This achieves that; there's still an incentive to upvote good questions, but there's an additional incentive to downvote bad ones. And the duality mirrors the Supporter/Critic pair of badges.
I'd call it the
kamikaze badge, since posting that many downvotes would translate to a major rep hit.
Think about this. 600 downvotes translates to 600 lost rep points, which I honestly think is way more than anybody is willing to spend randomly downvoting questions. Unlike upvotes, downvotes still have a cost, and I, for one, enjoy the comfort of knowing that my internet dollars were well-spent.
And in case some of you in the 10k range haven't noticed, there are several instances of presumably lower-rep users abusing the flagging system because flags are free and downvotes aren't. This question was absolute garbage, but it is not spam! Instead of giving these people an incentive to misuse the flags, give them a reason to downvote instead.
If people still think this seems like too much of an incentive for inappropriate downvotes, then don't require as many downvotes for that badge. Keep it at 600 for
Electorate but make it 200 for
Kamikaze. That sends a clear message that upvoting is preferable to downvoting but that downvotes are still an important aspect of the site.
That's my take on it anyway. Bring on the downvotes for this answer. ;)
