But if every vote pays out the same, why pay?

says the guy who makes more than everyone else

but yeah, this is my only beef with this idea. I think you need at least some front weighting to make people actually try.... though i think the current system has way too much.

"Making a content more popular" is the value later upvoters contributed, why not pay? They evaluate the results done by earlier voters, and confirm it by follow voting, done their work well.
