Project Gutenberg, Flickr, and Wikipedia (to cite just three examples... there are many more) don't pay their contributers money. On Wikipedia contributions can be mucked with by others. Yet these sites are all wildly successful.
- coryrc 17y agoShort articles on a specific topic require little coordination among contributors. A book used for class can't have redundant sections. Each part needs to build upon the previous sections (for math, anyway). The book should have a consistent style. Anyway, that's what khanacademy.org is for.
