Nothing beats Steemit,i have been on Facebook for 8 years but earned nothing(and also it is a negative community!).
It´s simply true that Steemit and it´s Community got the Capability of Changing your life but even more important, the life of others.
This is the best community indeed where people can help others without even meeting or the hope of meeting the people they have helped.
We can also help others come on to Steemit and may be their lives can be changed for the better.
Facebook is just a platform for people to show off or post some useless content... At least that's my opinion. I got an account but never really used it...
So Steemit is definitely the better choice for now ;)
