This time around I fully understand it! I tend to agree in principle - with one caveat:
All those Dapps should have more or less "equal" chances to receive Support from the underlying Steem Reward Pool mechanism to earn and empower their communities.
The amount of staked SP in each project will determine the level of support for each d.app, give or take some cross over curation activities. A community with 100,000 SP staked will receive 10x more of the reward pool than a community with 10,000 SP staked, and 10x less than a community with 1,000,000 SP staked. This is in line with the 'every SP counts' system of voting, although there is currently a regressive 1.2 sp tax on distribution, if I recall correctly.
Thank you for your support.
I don't really have a fixed idea of how much of the percentage of the reward pool should go in this case to SP holders, Voting for Witnesses or SMT / communities. But it is clear that projects who hold SP in their main account will not suffer of any kind of content abuse nor abuse of the reward pool this is my main point here.
We should design the Ecosystem of Steem in the way that the fundamental structures are easy to understand, easy to apply, with clear benefit structures and to avoid abuse.
What happens on the level of SMT and communities is all up to the users and developers how they wish to handle it.
In this Vision it is also clear that Steemit.com needs to become its own SMT Project / Community by itself without the only dependence of the main Steem Reward Pool.
I actually think that is already happening, except without the extra token. So in this case, Steem and (new token) will be distributed in each SMT/Steem-Engine project, each based on the respective stake.
So I think we are seeing less stake being used for 'quality content curation' and if communities like (off the top of my head) freewritehouse, thewritersblock, steemSTEM, dtube or others want to give their own tokens for their niche content judged to their own quality standards that they device, they will also deliver Steem in their votes to the level of staked SP.
With more communities coming in, there will be pressure on the Resource pool for transactions and account claims, which will create an SP sink. This is the idea, anyway.
