What we can all agree Steem is; blockchain (distributed database) where shareholders decide what new entries to database gain what share of the issuance of newly minted coins with one click of an button. That's the most fundamental core of Steem.
We're more like a traditional company than many other blockchains since shareholders play very important part in this ecosystem. but that's offtopic, the point is Steem can be both: social blockchain and serious journalistic one in my opinion. Especially when SMT's come and everyone can run their own "company" (mini Steem) here.
