This was an interesting article. The issues stated here are real issues that will face facebook if Zuckerberg decides to go into the cryptoworld using the steemit template. What if he decides not to?
What if he creates a template that fits the facebook system but still rewards users. In steemit, there are certain limitations to how content are presented e.g posts should be original content, posts should be of a certain length etc. Also the focus on votes gives people the need to follow and interact on content they don't like or know anything about while facebook relationships are made based on similar interests and likes.
Facebook has the platform to do so much in the crypto world and I believe steemit still needs to do more to counter facebook if Zuckerberg decides to join crypto.
