Steem is the blockchain of go-getters, overachievers, the ones who work when no one is watching, and help those who no one else will.
For me, this speaks volumes. You've described almost perfectly those who seem to be here for the long run, those who've stuck around. Those who aren't any of these drop by the wayside.
I have seen more done to progress the human race on the Steem blockchain than any other blockchain and I believe the potential is second to none when it comes to the future of our society.
Amen to that!
