I'm a fan of live feeds. I watch the Chris Pirillo live feed quite regularly and this year at PAX I was introduced to the Desert Bus marathon. You can go here: http://desertbus.org/ to learn more, but what it basically boils down to is a group of people from LoadingReadyRun play Desert Bus until viewers stop buying hours for them to play. They're currently on their 2nd day of playing and have raised over $23,000 so far. All the money raised goes to Child's Play, which is awesome. They have two cams set up, one watching the game and the other on the people playing the game, who are surprisingly entertaining. This reminds me of the 448 team that tried to beat the 4 3D Zelda games in 48 hours last year. I watched the bulk of that and was blown away that so many people donated money to this kind of thing. I love it and I'm happy to see more. Check it out!
