What obvious advantages does steemit have over facebook ? In my opinion one of the potential reasons is a fact that here (in steemit) people tend to write post about something, about some kind of knowledge. Facebook on the other side is mostly about fake profiles, fun-profiles which are always redirecting to there web pages with ton of adverts and almost zero text. When i scroll thru my wall i hardly can find pictures of my REAL friends. Only chat function works fine, but we all know that our conversations archive will be stored like forever on their databases.
