Fantastic video! The audience certainly seemed intrigued, which is further evidenced by all the questions you got later on.

Just want to make a slight correction, someone mentioned DTube and said that it was part Steem-blockchain and part centralized. In actual fact both parts are decentralised, the videos are saved on the IPFS network, which is a decentralized network though not a blockchain. Even the webpage itself, which hosts the client video code, is on IPFS. The aspects of DTube which remain centralized are very minor, and they're working on decentralizing those too.
