Imo, it's just a matter of "ranking territories" based on some metrics like amount of posts, zaps, comments ... activity in general.

Territories will have network effects themselves. You won't want to post in some territory where no one else is posting. You will post where everyone else is posting.

And market forces will hopefully take care of the rest (unprofitable vs. profitable territories).

The question is just: Is every territory a "winner takes all" game? Or will there be competition for ever (for some)? If so, why? Because people start rallying behind founders for various reasons, including personal? That's left to be seen, I guess.

We're still early. :)
