1 - this is a good point, but I'd like to expand on it - it does not have to be address book.

I have helped thousands of people exchange contact info after meeting in various niche chat rooms first, but you can flip that and have your irl friends meet you in decn-chat dot org click the 808game room, we can meet in there and pm/dm a code word or something and make each other contacts in various ways.

Your point is something to keep in mind though, ultimately I think we also need apps that can display a qr code like a one time pad to give someone contact details or any chat rooms to meetup in, Other methods of exchanging info about contact and chat room / chat app options should be added to whatever is going to be really good.

2 - I really agree with this, I spent some money and time on rocketchat development to give an optional 'open lobby' to anyone who enters, just pick a name and you are in.. then if you want extra abilities you can add an email or verify or whatever.

easy to get in is important indeed.
