There are also Mannabase and Grantcoin when it comes to basic income. UBI sounds very interesting to me because it would free us to persue what we really want and not be stuck doing jobs that we may come to hate and be detrimental to our health.
I'm looking forward for the steem community to grow some more and then asses it's impact in the developing world.
Later edit: Mannabase is a rebranding of Grantcoin
