Personally, I think one problem with evaluating talks purely on written proposals is that the process misses out on whether a submitter is able to attract the audience's attention, and to convey their points within the allocated time.
Written proposals can be heavily edited; talks on stage (especially if there isn't a rehearsal beforehand — most conferences wouldn't have the resources to do this) can't.
This is our 7th year and our first time running it virtually. Happy to answer any questions about the conference. We’ll also be publishing our notes about how we ran a virtual conference afterward.
Hope you enjoy!

They're on the Confreaks youtube channel, and we'll release individual talk videos a few weeks from now.
