i think Mark Zuckerberg should not make a mistake of doing the same thing as steemit. Facebook as its own way of doing things which can not be similar to stemit. he should keep his original conception ideas and project on more other poweful options but not into cryptocurrencies.
my point is that if people are now paid on facebook which was not initially, this can cause confusion and social media deviation. for marc to be successful, he needed an original and strong idea. however, making the same thing as steemit will not increase anything on people and may lead to a decrease of facebook users.

i do think that Mark is really bright and all surrounded with thinkers and should try to bring something original and not copied. for example, including various options of cryptocurrency users to make exchange or Facebook can play as an intermediary between cryptocurrency users.

ended, if Mark Zuckerberg can turn facebook into a cryptocurrency thing then he should assume use more innovative ways to attract people.
