Interesting bullet points but I keep clicking on these kind of headlines waiting to hear someone come up with a good method for how to balance an IRL audience with real time remote online participants in a way that fosters interaction. It's not even common to let remote attendees into Q&A etc so there is rarely any benefit vs just watching the event vod on youtube. It's an unnecessary blocker to a potentially much bigger audience and reduces the overall value of assembling people with like minded interests together in the first place.
