Some great information, definitely enough to get me interested enough to look into this a little bit more. It was also great to have the demo to see how easy it is to get started with it and see some of the different concepts in one quick run through.
The pace of the opening was a little slow, but I guess it's hard to pitch it right so that everyone is with you by the time you get to the demo.
For the demo, the dark colour scheme in your IDE might not be the clearest for all participants. A light theme might be a little clearer.
Great talk! Was still very digestible for someone who has a basic understanding of TDD. The example and demo was clear as well. Pace was right on.
