Why do we talk the way we do?

Hey,

I'd love to know if any of you have any thoughts on the following...

When people are talking in a messenger-like app one-on-one it's not much different to how you would talk in a sealed white room, you can add people to this room but when conversations are scaled beyond a small group of individuals, group chats fall apart. But i think there's a certain quality to these types of conversation, in that they can be constructive and open ended.

So what i've seen so far is the common approach to structuring communication at a large scale is through imposing a structured theme based topology, like reddit or any comments section. this is in my opinion turns the conversation into a debate as it's topic based and so therefore inherently terminal.

There's twitter of course but i think it's more equatable to other broadcast media like newspapers and such, there's a conversation happening but one that doesn't really involve anyone talking to each other.

So my question is does anyone know of any examples or have ideas as to how you would scale a group conversation to say 10,000 people?

Kind regards, S
