I have just learned that there is a video on WWSAPI at Channel9. Back in October of the last year, Yochay Kiriaty, Phil Pennington and myself got together to talk about the API. Yochay and Phil has come prepared with a long list of questions. I have tried to answer all of them. It was fun discussion. The delay in publishing the video was caused by an issue with the recording. Yochay was able to fix it recently and publish the video to Channel9. Check it out when you have time. If you have any questions, please let me know and I would be happy to answer them.
