Yeah that's a good point about reply-guys.
As much as I think that sort of moderation is great to have, I wonder how much it will limit their growth (which might be ok).
It's also a balance because if there is no interaction, if it's really not a chat room and is just a live show then I'd much rather just listen to a podcast on my time, at my convenience, with better audio quality and "is my mic on" edited out.
…It's really not fun to listen to, though, it is just a WebEx meeting with even worse audio.
