All right, the speaker was great, or maybe not, but you found the content interesting. You walk out of the presentation with a million more questions or thoughts to share with the audience, and maybe the world, but you never got the chance.

First, do we stand to gain from capturing even more content, and allowing collaboration to occur after the conference?

Do you think a speaker wants to hear more from the audience, and the audience wants to hear more from the speaker--post conference? And what about all other interested parties, who did not get approval to book a flight to attend?
