Because of the encrypted content I have an idea on who this is. I find the whole thing interesting. Is it possible for it to be a mutually beneficial setup? Do those people that pay for the subscription get enough in return for what they paid for? If there are a lot of people that subscribe, I don't think the group's voting mana can handle all of them, and some might get less back.
I wasn't really a fan of the premium services, but I think the encrypted option can be good for decentralization purposes. I am on the fence on the curation part since on one side they are still on the blockchain and people can vote on whichever one they like, but on the other, I think 'buying' votes is frowned upon.
