Very interesting topic, with a lot to cover. I'm glad I went, I wished I could have stayed longer. I'd also cast a few stones: 1) a 2-hour lecture needs a break/intermission, and 2) Hold questions until the end (perhaps of each session) and 3) start on time.
(RE: holding questions: in my experience, at least 90% of audience contributions *during* the delivery of a lecture are at best not useful and at worst mood-changing. Though I love a group discussion, lectures are a different kind of forum, and I've personally lost all tolerance for audience members who hijack a presentation without considering whether or not their questions are useful to the audience at large. My brain then, despite any argument I may present it, tends to blame the presenter for allowing this). Overall, it was a great presentation of a complex and bold topic, well delivered and engaging - I'll definitely be back for more.
