Its interesting.
I actually I think its useful to view by designers/developers because of his broader comments from about 57 minutes on.
Jeremy I think has the best overview of TW. He is always contextualizing it in the context of browser, open-source, plugin need (problem of you can't have foresight), and edge of viable developments.
He is a very clever man.
TW is a shared-subset of his brain.
Best wishes
