Decentralized mean nobody is in control. Another way to put this is that everybody is responsible. Steemit Inc is working on the infrastructure and that has been their philosophy for some time (especially since @ned took over) So what makes Ethereum better and stronger? It's such and inferior product to EOS. But there are so many amazing projects like SONM, BAT etc. and most of the ICOs and billions of dollars worth funding happened through ETH. That contributes to the value greatly. So to build STEEM, interact with the DAPPs and make them great. Stronger the DAPPs are stronger the STEEM ecosystem will be.

My regular used DAPPs are @steemhunt and @dlike I also love visiting http://dpoll.xyz and now is the best time to get into STEEM Monsers. They totally revamped the game: https://steemit.com/steemmonsters/@vimukthi/congratulations-steem-monsters-for-finally-making-a-good-gameplay-experience-for-my-investment

Happy Steeming!
