People are getting busy day by day. They have less idle time to spend seeing garbage of others(sorry to say)! There is no free launch, so steemit will beat FB vary rapidly in near future. It will happen firstly in fast countries(Country with higher education level & Higher per capita income). Users of less education level and lower income countries will linger dominance of FB. But I think red light is blinking behind FB, Steemit is getting more green focus day by day.
