I must admit, I watched the presentation. Two things were obvious. One was that, as a long time programmer in PHP and Javascript, this was way above my head, AND that the presentation only brushed the surface. It was clear that a whole bunch of detail was missed out. I think that the developers, as represented by the awesome Rachel Baker, need to think long and hard about HOW they show us how to use the API, and what I watched yesterday was NOT the way to go. They need to build a demo front end that is fully commented in code so that we can take it apart and see it work.
