I agree with Alan and the standout keynotes in my mind were a single voice talks (my view is probably slightly biased as most of the keynotes I’ve seen in the last 4 years have been at #altc where there is a very rich twitter back channel). These also work well as recordings, a resource people can revisit at a later date and hopefully stimulate a long tail reaction/interest. Still important to make people ask questions but they may be internal reflections as well as out-loud. Voting/discussion on something like moral statements can be interesting but can be very time consuming particularly on the first vote
