Yes it will be very interesting to see over time how the network will grow.
I do believe the growth of steem and the growth of Facebook cannot be compared. As in the beginning of Facebook you could only join if someone invited you. With steem, people join believing they will make money - and then they don’t make quick progress - and quit. So it will be up and down on the platform of steem in the beginning
