These are all great points. I completely agree that we can't define Steem in terms of existing categories. Maybe that's the real answer to the question in my post: not that Steem doesn't fit into some traditional categories, but that it's really something unique and that it's in a category of its own.

I like thinking of the Steem blockchain as a mini Internet, like you said. I think we're just starting to see its potential beyond blogging/socializing, and I can't wait to see what comes next.
