So I just skimmed through your posts linked above (sorry I didn't have time right now to fully read them) but I really think you're on to something there. I would love to see an SP holding based subscription model for content.

Off the top of my head I'm thinking there could be a front-end where content creators can choose a subscription level, for example 100 SP, to have access to their content. So that means if I want access to that content I have to have at least 100 SP in my account and then when i click some button to access a particular piece of content it will "unlock" it by submitting an upvote from my account.

I think that would be really cool and, if done correctly, could actually incentivize a significant number of people to invest in Steem Power.
