I think Steem platform is better than Facebook because in order for Facebook to be on top in the market and earnings, they must sell information. Facebook also has a specific theme which they lock themselves into. Steem can create their own facebook theme if wanted. The sky is the limit.

The difference with Steem and other coins is Steem is not widely available on other exchanges. I believe the value of Steem is held down because of this. Why is Steem/SBD not widely available? My theory is that it has to do with the fact most exchanges require significant payment to list a coin. I feel Steemit CEO and developers do not wish to make the payments and instead allow STEEM to be an underdog in which popularity drives the need rather than paying their way into an exchange. I personally believe that the payments should be made to accelerate the growth of STEEM.
