Chat-based interaction certainly sounds like it could work for tech-focused events - I think for CCC one of the challenges is the sheer number of parallel talks, and keeping track of them. Pre-recorded talks definitely seems like the way to go and having participation in the chat for Q&A seems like it would work well for an engaged and "fast typing" audience. Thanks for your all your insights here - very useful to see what does and doesn't work for events. I think the move towards "hybrid" online and in-person events will be when it gets interesting.
