Couldn't agree more. It's as if the current Steem community are just employees of Steem itself. We need curators, creators, comedians, writers... In a funny way, we even need people who make things we don't necessarily enjoy or like, for it to be truly mainstream.
I believe we'll get there. We already have the frameworks and early stages of many of the above stated communities, now they just need to grow. In due time, I'm sure :)
