A number of folks — many of whom had Discord groups — have been using the Steem-Engine exchange and token creation facility to create "sidechains" of Steemit with specific focuses. It seems to have more or less become a *"people's version"* of the "Communities" STINC promised over two years ago. Anyway, many of these "tribes" also have their own tokens and reward systems. Your posts can basically become a form of "double dipping," because you get rewards from Steemit proper, as well as in the form of the sidechain tokens. 

I'd say the most prominent so far is PAL (Peace, Abundance, Liberty) which is an outgrowth of one of the oldest Discord channels, and part of the Minnow Support Project. But there are several others that are also worthwhile.
