Steemit, Inc is doing exactly the right thing by making sure the back end is capable of handling the onboarding of the masses and creating developer-friendly interface on top of the node interfaces.
Yeah, most will never know what is powering them.
By the way, I think much of the confusion as to what Steem is at the moment is caused by the fact that all the potential use cases of Steem the blockchain are yet unknown.
Yep, as more are born, more will be born. It is the way I write too. :)
