filtering

SwiftRiver is a free and open source software platform that uses a combination of algorithms and crowdsourced interaction to validate and filter news.

And they have a Drupal module: http://drupal.org/project/swiftriver

Could definitely be a complement to Visions Unite, it isn't a replacement, it uses user input but the focus is on automated filtering.

Data is agnostic. Information is amoral. Pointing the narrative-free fire-hose at the digital citizens of the third world does nothing to empower them, and U.S. politics is proof that More News just means More Influence for the person with the craftiest narrative. Once the saturation point is reached, even valuable information is part of the problem: no one has the capacity to sift and filter, and we fall back into the embrace of our trusted interpreters.
