hookyOkay, here's some comments, based on part of the Day 1 rebroadcast:
It's very well put together. Lange did an amazing job running the stream, as usual.
Casting is great also. I didn't expect anything less than that. :D
Only issue I've noticed is that there's occasionally some feedback on the mics, but that may have been fixed.
Feedback can sometimes be unavoidable in a venue that big.
