You have said it all in this post.

But if you live in a place where there is a great deal of poverty and economic hardship, the STEEM blockchain is changing lives, irradicating poverty, and has the potential to create a system which can alter and enhance entire communities.

Steemit is a life changer to Africa,the small upvote you give to an African promoter does a lot of good to them.

If you have ever wanted to leave a legacy in this world,Steemit is the best way to do it.

As you said Africa promoters are the most active,true....i also got a TV interview with a small station a few days ago here in Uganda.
We also have our first major meet up this saturday.

I wish many people see this post and it goes on the trending page,let me resteem it.
