I am still having some trouble understanding the ecosystem of steem. I am not sure how the smart-contract peg will be able to to hold value for long if just more and more tokens are created and there is no demand to buy and spend them? If everyone is just exchanging out the price has to drop constantly until the smart-contract implodes....

But if it works in keeping read value of the tokens and in filtering high quality material it is a great social platform. The ability to get paid for it should also generate more high-quality content.
I just haven't figured out who is paying for the content and work of curating buy buying steam dollars or why someone would buy steam dollars yet....
