People vote for good content, not in return for good curation. That's why the founders tried to build in an incentive system that rewards curators, so that reciprocity in voting wouldn't be necessary.

Personally, I'm indifferent to how people should vote. They should do whatever their gut tells them IMO. I think ultimately that's what's going to drive the site anyway, and ultimately what will make it palatable for your average person.

While I think it's admirable that people like yourself want to be good curators for their vision of how the site should look, the gut reactions of people are ultimately what will determine the curation if and when this site gains mass adoption. People who won't or can't contribute desirable content (read most future users) will only come here if they see what they want to see, nothing more, nothing less, regardless of how any of us here now feel about that.
