I am guessing this is a post-discussion? Did you recently do your speak in front of a live audience yet?
Yes, I gave it last Saturday. Hard to imagine a week has already gone by. I don't know how to compare various TED venues, but TEDx Beacon Street is one of the best because it's at WGBH Studios in Boston, which are very nice, and you can draw a lot of talent in and around there. Mainly, I have faith in the organizer, who has a license from TED that lets him draw a big crowd.
TED talks are amazingly varied. You might like this one from Simone Giertz. She's the one who turned a Tesla Model 3 into Truckla, a pickup truck, and got a zillion views on YouTube for it.
