Well I probably count as the masses. But one model might be a sort of web of trust. You start off with a few people who are ultimately trusted. And then as your web grows you can track who let who into the site. People who consistently let in poor members get their invite privileges revoked or are kicked. Have a reputation threshold before you can invite people.

For one, they don't even seem bothered enough to correct the "cache expired" continuation crap on the site, much less to build a new moderation system.

Second, if "poor members" get invited in large numbers, then the system you propose will fail, because they get to dictate what is good or not (by upvoting it), which will in term make them appear good (because they like/submit the 'good stuff').
