Is anyone attending Def Con this year? They have opened up this year's registrations to in-person and online attendance.
I attended Def Con 28: Safe Mode last year, and it was entirely on a mixture of discord, youtube and twitch. I believe it worked really well, especially in comparison to a lot of online conferences that has happened during the pandemic.
This year, I picked up the badge:
Apparently it alternates between an electronic, and non electronic based badge each year, but still contains a puzzle/competition. The firmware isn't out for this badge yet, but until then it behaves as a nice set of colourful shortcut keys for muting, volume control and a smiley for online chat 
If you haven't picked up a badge, you can still attend and join in the discord, and they have an expanded 'human +' role for access to more rooms on there.
If you're not attending, what talks have you found interesting? You can find videos and recordings of the talks uploaded to various village youtube accounts, but there's also the defcon media server.
