Beyond the scenario you describe, I have some apprehension around audience questions in these venues, as the questions are often enough digressive or part of some dominance/status game. For a speaker to aim for presenting for 25% of the time and fielding questions for the remaining 75% strikes me as lazy or a dodge in case you have no idea how to effectively present your information. Totally agree with you on the recorded talks, BTW!
