Thanks for opening this dialogue @aggroed, 
It would be so cool to simple see a Steemit inc. town hall discord set up for all of these discussions. Its the most neutral platform for these types of conversations to happen!
Regarding the structure of this on the blockchain:  This should be a multi proof of brain free market of ideas super structure, with zero leaders in my view.  That is what blockchain is for.   If we create committees as part of the top level, we will centralize and produce powerful gate keepers over time (as every other community in history has done).  We have an opportunity here to build something with a decentralized community structure, with organized committees operating below this structure voluntarily, not appointed.
