Allows user ratings of aggretated news & events.  Not a simple 'thumbs up / thumbs down' rating, but ratings on quality, authority, balance, trustworthiness, sources...  Still in beta, but going full bore in 2007.

From the website:

To address this critical issue, NewsTrust is developing an online news rating service to help people identify quality journalism - or "news you can trust." Our members rate the news online, based on journalistic quality, not just popularity. Our beta website and news feed feature the best and the worst news of the day, picked from hundreds of alternative and mainstream news sources.

This non-profit community effort tracks news media nationwide and helps citizens make informed decisions about democracy. Submitted stories and news sources are carefully researched and rated for balance, fairness and originality by panels of citizen reviewers, students and journalists. Their collective ratings, reviews and tags are then featured in our news feed, for online distribution by our members and partners.
