A Grand Unified Theory of YouTube and MySpace
Ant writes "Paul Boutin's Slate article explains the factors contributing to the success YouTube and MySpace: they are easy to use (usability), and they don't 'tell you what to do.'" From the article: "Both YouTube and MySpace fit the textbook definition of Web 2.0, that hypothetical next-generation Internet where people contribute as easily as they consume. Even self-described late adopters like New York editor Kurt Andersen recognize that that by letting everyone contribute, these sites have reached a critical mass where 'a real network effect has kicked in.'"
(which is relevant, because once you have other people deciding what is quality and what isn't, the spammers want to jump in, pretend to be anonymous, and say Hey! my adverts are quality stuff everyone should look at!)
