One thing that is missing from the above list is the managerial roles: editors and so on. Who decides the content to go into each issue? There's a lot of good curated content here already. Who decides on what themes go in which issue?

I think there needs to be an organizing force, other than the whims of Steemit curation. I could foresee a small team of editors taking the best curations from various subjects. And then an Chief Editor organizing the Editors into a cohesive group.
