Great talk.
Interesting topic.

Very good talk.

This keynote was really different from any I've ever seen before. Seb is a great, relaxed and animated speaker who managed to make the entire keynote seem very spontaneous. It was a great way to open what is always an amazing conference and got the audience ready and rearing to go for the rest of the day.
