Wow, thanks for letting me know about Steemporium, I hadn't heard of it. There seems to be more and more being built on the Steem block chain it's hard to keep up, and that is really amazing. While I think Dtube and Zappl are incredible and bring a ton of value to the platform, I believe you are dead on in the fact that the organic growth of Steemit turning into a social economic platform is where the real growth of the Steem block chain is lies.

My vision for the Steem block chain is a complete social ecosystem comprised of a vast social media delivery and consumption system of blogging, communities, video, micro blogging and every day economic marketplace where Steem is used for everyday goods and services. Could you see an Amazon or Ebay like marketplace being built on the Steem block chain where all transactions are conducted in Steem? I absolutely can. Now I'm beginning to see the very broad scope of just what the Steem block chain can become. Reaching all levels of every day economic usefulness. It's quite humbling to think about and leaves me in awe. It truly can change the world as we know it. From every day transactions, social media, banking, there's really no end in sight to what problems it can solve. With the right leadership, innovation and boldness, the Steem block chain could quite possibly become one of the most valuable platforms the world has ever seen. Very exciting and quite liberating at the same time.
