Well thought out article, you have managed to articulate exactly what I was thinking about the future of steem.

When I first started on the platform, I would debate at length with people thinking that steemit would replace facebook. But Ive always believed that it is more likely to replace long form content platforms such wordpress, medium and the like.

There are endless applications for the steem blockchain and synergies amongst use cases for example, a steem based application which delivers long form written content with video. Eccommerce stores with built in video and blog channels an evolution to the home shopping business model.

I agree that earning just by blogging will likely become unsustainable, but as you said there will be many other ways in which steemians will be able to become successful through new experiences developed to utilize the steem blockchain.
