"What is the ecosystem is all the developers who are banging out code. These individuals (and teams) have created hundreds of applications along with thousands of updates. It is now to the point one individual cannot keep up with all that is going on."
This is the real key to future success. At SteemFest I was amazed by all the great apps, many of which I had not heard of before.
This is just the beginning of a veritable Cambrian explosion of life on the Steem blockchain.

It is one of the reasons I'm so excited about joining @utopian-io, to be exposed to all the great new apps and be able to enable their development.
