Good site also to check out is our Guides [1]. We've collected research on user engagement into a format that should be easy for newsrooms to adopt to create better discussion. [1]: http://guides.coralproject.net
The feature I want is, as a site user, to apply my own set of filtering and moderation criteria. E.g. "I don't want to see comments posted by user XYZ, or containing regexp W. Any comments by user ABC, or upvoted by ABC, or containing regexp D, go to the top. I trust the moderation of site trollblocker.com" I don't see these kinds of ideas represented in the user engagement research.
