One great aspect of Objectivist Conferences is the opportunity to ask questions of the intellectuals presenting their ideas, immediately following their talks. Coming up with a thoughtful question can add depth to the topic, and help express misunderstandings that might be shared by a lot of the attendees listening. However, Q&A sessions have a limited amount of time, so if you're going to take it up with your question you might as well do a good job. I personally find it pretty intimidating to get up and ask a question in front of the large audience, however I can tell you a lot from an audience perspective.
