Quote
if you had a show where they had comments attached to each episode, then those comments sort of live forever on that episode.
Episode 63: we're hovering at 500 feet that is, hello everybody. Tom once again (approx., from transcript intro) 01:06:18 (play audio from this timestamp, opens in a new tab)

Summary
Dave credits Alecks Gates with an early, valuable insight: live chat and comments aren't the same. Live chat content gets lost, while comments attached to an episode live on forever, so people can come back and respond to something in that episode.
