Imagine a conference where half the audience was heckling and
questioning the speaker near constantly. And not just unfounded
heckling, but well-researched contrarian jibes and zinger queries.
Imagine holding your attention on the speaker while their presentation
was being expertly critiqued by the people around you. Now imagine that
all that was happening silently, you could hear the feedback but the
speaker and most of the audience couldn't. Imagine that backchannel
conversation was open to anyone with an internet connection. Then
imagine trying to concentrate on anything.
