You are thinking about chats like a soapbox perhaps, by calling them posts, and trying to make them cater to a network. They are conversations, when you add people, it is so they can join the conversation, naturally that's not your soapbox.

So you just don't do any of those things you mentioned, people rarely broadcast using group chats. You are trading quantity and breadth for quality and depth by choosing just a small group of people to keep in contact with meaningfully.

Social media does really help people stay connected no doubt, but it breeds shallow connection habits, and I wager it makes less meaningful connections out of people who could have been very close had they not been given that feeling of connection through shallow means. Like eating a fast food burger instead of a nutritious meal, you are satisfied so you don't seek more, but you robbed yourself of a better opportunity.
