This post, containing the wise words "fwe fe", has already made more than many a good post with real content in it. (Edit: some rewards have been flagged away now.)
It's not about being annoyed because somebody makes more than you, it's about how ridiculous it makes people feel when noise makes more than content, even when that content gets over 100 votes.
Bots gone wild? Following votes? Sock puppet? Who knows.
(Edit, thanks @nikolai:) The problem goes deeper than votes-for-noise; posts with 200+ votes making under $1,- are hard to explain to new users when they see noise or even equally good posts make a lot more, with under 20 votes. The gap is too wide and doesn't seem to be closing at all.
Would it be possible to change the reward formula into something that also includes both the number of upvotes and the reputation of the upvoters? Or would that just invite even more botvoting?
I was thinking about rewarding, for each vote, (voter reputation / a) + (current formula reward / b), with a and b calibrated to give a more even result without upsetting the total reward pool too much. Or something along those lines 8-).
