I agree. I think we need reputation mechanism. From restaurant and Amazon reviews through travel recommendations to written content. I want to read what reputable people have to say or people similar to me or people without history of spamming nonsense.

Current system is too easily gamed. If it means we need to sign everything with real name/ID let's be it. There is a place for anonymous Internet but life is too short to go through piles of trash every day to try to find a nugget. At least allow others who already found it to sign on "I found out and it's interesting" promise.
