You're right in saying that we are all shareholders, and as such all our efforts will be directed at making our investment more valuable. That's how Steemit will rise to be a powerful community over time.
Your post really showed how unfair FB is when you look at the value of what we give it versus what, if anything, we get out of it. I feel Steemit really rewards our attention and ensures that those who are vested reap rewards in proportion to their commitment. Time on Steemit is never wasted. Can't say that for the other social networks.
