RE: Understanding SMT Features
I don't think it would be for the best. I believe many of us are beginning to see that the POB system is best made for small communities and not as an all-purpose voting system. As a previous Steemit blog article brought up, it is not fair to subject art communities to the stake-weighted voting of a whale that does not appreciate art, while an all-purpose stake-weighted system does this.
Let me put it another way, frequently the people interested in something like a stake-weighted curation system leveraging crypto would be crypto investors. In the case of Bitcoin fans, a very large amount of these members are red meat eating capitalists that might not value vegan recipes. In this case, it would be better if we could separate the vegan fans from the steak-loving capitalists that are only interested in curating moonboy predictions. So, the main solution to this problem is to allow for many smaller, sovereign POB systems.
As far as managing different groups of people this can be addressed with the implementation of communities using hivemind but you are probably right if we consider that value distribution using a single token can be problematic if one community has way more stake than another one. I still think that we need another vehicle to distribute steem to as many hands as possible other than just with block rewards and "interest". Maybe we can reduce the rewards pool to a minimum and just allocated to steem related content.
