I think Steemit should be used for community good, not self good.
I am part of a network in South Africa whos sole aim to help as many people as possible through technology and self sustainable means.
What steemit needs is foresight, and by using that foresight, will be able to predict to some degree the future. If you can predict the future, you can predict the needs of the people on that future.

My advice, don't tell people to come and join Steemit. Show them why they should join. All the greatest movements and leaders the world have seen have been driven by selfless individuals whos main aim was to debug societies and humanities.
Show them by helping your local communities through steemit. Show them by using steemit to change someone elses life, not yours.
