Bumblefoot "tawked" for about 2 hours.
The set-up there seemed to be super cool for this type of thing. During the tawk, Bumblefoot and Blake Ian (the host) responses were on the left side of the screen. If you signed up & logged in (which I didn't), you could see/post the audience's comments/questions on the right side of the screen.
After the tawk was over, I could see the questions/comments that Bumblefoot & Blake Ian picked to respond to (apparently, they would just highlight any fan comment to reply).
People can go to that site any time and continue to post questions to Bumblefoot. He can log in and reply any time he feels inclined to do so.
One cool reply about Bumblefoot's ideal future GNR album:
Ron "Bumblefoot" Thal Perfect GNR album would be one we wrote together, where everyone plays only one track, and you can identify every member in the sound
