I do not think Steemit is Facebook , it is not Facebook and it will never be, it is better than Facebook and has the potential to be big and better than Facebook , steemit is in its early stage and years to come will tell , it has great team behind it and trust me as soon as the true potential of steemit is seen by all i don't think there will be any social medial platform that will rival it and we should not be surprise if sometime in the near future there is an upgrade to the design and steemit to make it look more like Facebook or so much more better
