Free Admission - Share The Truth
Here's an intersting P2P social software approach - Share the Truth website has seen Al Gore's The inconvenient Truth and feels that it is such a seminal, must see film that they are willing to pay for you to see it, and have developed a forum for others who have seen it and are willing to fund others to see the film - contributing to a spreading of the word!
"Sharethetruth has one goal: to relentlessly encourage the viewing of one very necessary movie. It will promote An Inconvenient Truth, ask others to help, and explore every sensible means possible to advance public awareness of its lucid science. I am in no way affiliated with Paramount Classics or Participant Productions, though will certainly write them for assistance in this cause. As of June 15th, you can donate to sharethetruth! Following are the timeline and future plans. Your ideas for improvement are welcome, so please contribute them at the forum.
