Runter, it sounds like you wouldn't want to go this far, but I've had an idea on my back burner for a while that's a tool to help with this kind of stuff. Basically an aggregator/reddit-clone with editorial tools built into it. The biggest obstacle I've found to maintaining this kind of thing long-term is keeping up the weekly commitment (whether on your own or finding contributors).
I did this for a year with a similar genre to muds (http://ifurls.tumblr.com/), by hand, so that's my experience anyway. Maybe having a team doing it will alleviate the problems I had.
