All writing is communication, whether it be novels, plays, scripts, factual, blogging, or whatever.
And all writing has an intended audience, be it the smartest 5 people on Earth (eg James Joyce's Ulysses) or everybody in the world (eg Harry Potter).
There is nothing wrong with writers communicating solely within Steem about Steem. After all, that adds value to people's lives.
But IF the stuff we write COULD easily be adapted to speak to people outside the platform, then it probably should be tweaked to do so, and republished outside the platform, with links to the platform.
That would add value to more people's lives, and more value to Steem, as well. :)
its like steemception my friend... the ninja move.
