Great post, and I agree completely that we need to build out each individual category. I also recognize (more recently, in fact) that Steemit is quite literally the most interesting thing that I've personally seen happen in the technology / cryptocurrency space in over three years. In many ways, it's the only thing I really want to talk about right now, and I don't think I'm alone. All that means, I think, is we have a chicken and egg problem. Steemit is exciting so we want to talk about it. Talking about it too much won't grow the user base of people who want to try out a useful social media platform which could reward their efforts directly.
I think, at least, posts like this are a good step in the right direction. :)
