A small pile of good links:
Steve Rubell thinks search will revolutionize social media. He also think news aggregators should “come clean“.
Robin Hamman on how PR people should deal with social networks.
Tom Scott on how it’s unnecessary to build trust into networks as the human brain will assess that better anyway if you give it the right tools and data.
Very interesting article from Slate on the limits of Wikipedia (I spotted this through starrjulie on twitter.)
