We would have Twitter the API, and Twitter the umbrella network. You might want to promote a sub group into the larger network, or you may not - similar to reddit in a way.

I imagine invite only groups, time-limited groups for concerts/conferences/sporting events, location-locked groups that you dynamically join and leave as you move around.

I may just be describing iMessage or Slack at this point.

I would definitely like the idea of being able to add a private channel whenever I wanted one. Something like #{myusername}-private-{whatever} and then I could approve or add users to the channel
