This is really thought provoking @ogoowinner.
Truth be told, if reward be removed from steem, I don't think a lot of people will still hangout here because am kinda optimistic of the fact that Facebook has some kinda rishi rishi it's adds to its platform that will always make users stay and that is likes.
Truth is that likes are free on facebook, but at least you will get a handful of it, no matter how amateur your posts looks nor when you started blogging, with lots of comments too.
Here, everything is strict. Only a few cartel will show you love, nor comment and that's why a lot of minnows give up which is something that never happens on facebook irrespective of the fact that it's free.
It is not about showing love, it is about making here more interesting without the rewards.
