I have both. Each serves their own purpose. I would not use facebook to get information but rather would go into steemit to get it.
I use facebook to have friends and family and see how they are doing and how children are growing.
Steemit involves more thought process and its a great way of having an account that can pay you for expressing your thought and emotions.
Looking into the future, more people will be steeming! Its the future :)
