Is there a point where even 30,000 quality secrets per day are going to be too overwhelming and better off screened somehow anyway?
I run sites with anonymous submissions and lose a lot of time screening some really offensive crap, but even with 30k decent submissions per year, I'd be keen to filter those pretty strongly. e.g., if there is no expectation from users that they'll see everything decent that they submit, just approve the first x and flag the rest for later or never. Will even the most committed reader have time to go through 30k a day? As far as I understand PostSecret, they aren't really localised and probably not categorised, right?
Also, is anyone aware of any websites crowdsourcing moderation through Amazon's mturk? It seems like that might work and it sounds cheaper than moderating 30k secrets a day in house (but it would probably be less accurate).
Interesting idea to use mturk, it would probably be cost effective but the turn-around time may not make it feasible.
I wonder if the app's user community can fight against it by using a simple karma/points rule like on HN or Reddit. Too many down-votes and the post doesn't show up.
