All good points. And I'm going to sound like a pitchman for Tender (http://tenderapp.com) :) But that's kind of why I liked using this to create a minimum viable version of this community. Tender is very friendly with email. So new things submitted to be reviewed will get blasted to submitters who have their email alerts turned on. They can reply via email. There's also queues if someone wants to put something in their queue so the duplication factor might go away some.
