I've seen a number of posts about developing out more tags or sub-categories and it got me thinking of the incentive structure already apparent in the Steem platform.
Purpose: Give users the ability to decide on which sub-categories should be developed and maintained.
Parameters: Users are able to 'vest' SBD or Steem Tokens into a sub-category of their choosing in order to amplify rewards within that sub-category.
Explanation:
sub-categories that are heavily invested into will generate the most content;
funds that are vested can be withdrawn by the individual who invested to encourage transparency and maintenance;
SP and SBD both generate more SP and/or interest like a normal user account;
generated bonuses are redirected to content creators and/or curators within that sub-category
creates a social contract that could be delineated in announcement post (preferably with verifiable escrow contracts that can be built into author post creation processes
