It is truly enlightening hearing someone else elaborate on your personal thoughts. I got into Steemit by invite, and since, grew from curious to avid multi-platform user within a month! I agree, my interests similarily, call for some kind of exchange between the value of different types shared content.
Facebook defines categorically each content type in a value set to publisher's directed audience. I guess that metric on Steemit is in the measure of metadata "weight", how populated user engagement each of those meta tags receives, but for everyone else, you just gotta be sure. Establishing a practical time = money = art sort of capitol cycle is all a new world for commerce, how people make a living these days are as varied as the lifestyles we're now heavily marketed. Facebook effectively converted a portion of its user base into commercial marketers and in addition, attracted real companies to market on their platform. It's incredible how that happened in such a short time (maybe since 2009?).
Steemit is where it's at now. People spend so much time online, communicating at the least, might as well earn something while you're at it.
