One interesting feature of DE{CODE} is that the conference is streamed live, but sessions are all pre-recorded and presumably polished ahead of time.

I've attended and presented at online conferences with this format, and I really like it. As an attendee, it makes it much more flexible to watch presentations when you want. As a presenter, it allows you to be available for conversations with attendees during the presentation. You can be actively engaged with the viewers instead of focusing on the presentation. Plus, you can create a very polished presentation if you like.

Brian's session sounds pretty cool.
