Not to pile on here, but does anyone have the slightest idea what this means:

"Yes, the default discussion on an article page is that between the author and people the author responds too, and people they talk to. It spans two degrees of separation, but it is centered on the author.

However, on a specific topic, a reader creates their own group chat among their friends simply by responding. So it's not like the author has a monopoly over the discussion. Anyone interesting or connected or active can draw people in to a rival web chat.

May the best moderator win!"

Degrees of separation, group chats, rival web chats...?
