"People should be upvoting articles based on quality"

Yeah, but by what measure of "quality"?

I don't hang around here with the intention of curating non-participating readers news feeds, I keep coming back for the interestingness of the discussions that result from submitted links. The true or falseness of the linked article is way less important (to me) than the opportunity for interesting comments.

('course, maybe _I'm_ doing it wrong...)
