Two videos I really like about the power of bringing more voices into the game.

Also, these make me think, what are the defining characteristics of success in the web environment? Success is usually about removing barriers to information sharing and lowering the bar so that many people can participate (YouTube/Flickr/Facebook/Blogger/Twitter/Digg/Delicious/Wikipedia/etc...). This can create lots of "garbage", but it also creates a very rich environment for observation. It also empowers individuals to self organize without larger structures.
