I was just introduced to arcade.city today thru a news article. http://cointelegraph.com/news/arcade-city-decentralized-blockchain-based-answer-to-uber Then with a little more research I realized that they are NOT decentralized at all, it is just an uber cloan that is jumping on the ethereum bandwagon. I am pretty sure it will be extremely complex for them to move everything to solidity, the code for daps. Wouldn't it be great if we had an uber killer app that was truly decentralized via the masternodes? and everyone that rode the 'dash' would have to pay in dash!! anywho, just an idea I wanted to throw out.
