I am all for setting goals, but it might be difficult in the context of the Steem ecosystem to ensure progress and achievement without some form of 'central' management.
Micro-monetary- manipulation / incentivisation might do the job, but that would likely depend on one+ large stakeholder being willing to use their stake to that end.
Which would in essence be that very central management...
But I would still say Go For It.
