You nailed it. Some tokens have other ways of earning but most all have a community that brings disscussion around a shared topic. You can do those topics just through their community tag (eg #sports) or through their dedicated sites (https://www.sportstalksocial.com) and earn rewards. Some tribes reward their own site more than one that just uses a tag but its really tribe specific.

Questions are how we all learn :) Hope this opens up some new potential for you!
