The Social Graph API page on Google code exemplifies the future of multimedia learning and why open source is being so productive relative to proprietary software development efforts. A two and half minute YouTube video introduces the concept. Links are included to documentation and examples. I've got code, examples, documentation, and even a human giving me a tutorial. (This one intro video could easily be expanded to series of step-by-step instructions.) Five developers might jump on the Social Graph API or 5,000. The right five might matter more than having 5,000 developers. What matters is two points. First, beneficial multimedia is no longer expensive to produce or distribute. In fact, it is becoming a basic skill of people everywhere. Second, the distributed nature of open source mentality encourages people to provide information in economical paired-down forms—even if the code is not open source but merely an API.
