You can already select on Damus to reply to one person if you want. There’s a thin line here; sometimes it’s more fun to be in a small group chat/thread n other times it goes out of control.

I agree it’s fun when your with a small group. I think the comments aren’t even too much of a problem.
Someone will shaka a note deep in a thread we’re mentioned in, and then a few seconds later someone else will shaka it. I guess Twitter is like this too, so maybe we just need a mute and not worry about anything else
