I think Steemit is a bit different as it's more about the content and quality content. Unlike facebook that's all about appearances and social standing. On Steemit there are people who try to fake it and abuse it but the better content producers do tend to do well, while commenters can make a small profit. Fake commenters are pretty easy to discern from genuine ones.
So yes, some similarities, but Steemit provides good content, Facebook, Twitter, Instagram etc. are just junk media.
