True. There are some features steemit could borrow. Although in regard to that one of enabling contact with others more privately, in my opinion, would do more harm to the platform.

I think that one of the strengths of steemit as a platform, is its 'Transaprency'

By making sure that every transaction is in the open, people are comtrolled from colluding or doing bad things behind curtains. For a money incentivised social media platform, this transparency is in my opinion important
