Dan Gillmor targets Reputation Systems Required - an issue that seems to keep popping up. I remember having this discussion on Ecademy last year.
With the multitude of blogs and people coming into our lives through the cybersphere, we do need some kind of way to gauge reputation. We should have a feedback channel with polling for specific criteria and an icon signature that could only be earned. This would provide some way for us to define sites based on a tagging system that we can all agree to use and vote on. It should absolutely not be about popularity, but we should collectively define what conceptual issues are important and create a polling system. Safety would be a good tag - everyone is worried about tunnel sites that open you up to hacking.
What are the issues that build site reputation in a cyberworld?
