> how do you manage discovery of other users

Here's my personal profile on 9social:

https://github.com/dharmatech/9social-user-dharmatech

Each profile has a `following` file which shows who they're following:

https://github.com/dharmatech/9social-user-dharmatech/blob/m...

So, once you know someone on the network (now you know me!) you can see who they follow. And who each of them follow... And so on.
