Personally a would much rather have the STEEM blockchain promoted and not just one of the apps built on top of it (steemit.com).

There are some inaccuracies with the promotion. For instance you say "that steemit pays you to blog" which is not true. Steemit is a company that hosts the steemit website and has the core developers of the blockchain. However they do not pay bloggers. A more accurate thing to say would be "you can earn money by posting on steemit or any of the other apps that connect to the steem blockchain".

Overall I think it's a good promotional video.
