Steemit is awesome so far, and I just got here. But you are comparing two different types of websites IMO.
Either way, I don't use Facebook anymore. I'm confident people will use it less and less in the coming years. Lack of privacy & narcissism somehow became a social norm over the past 10 years - but I think this will eventually reverse itself a great deal.
