It's great to have tutorials like that. 

However I am a firm believer that we should go the extra step and provide some 'higher-level' tools than SteemJS to help developer create bigger STEEM apps more easily.

I believe if we had a good 'boilerplate app', for deploying a simple react-based STEEM app, with STEEMJs, some 3rd party services like AskSteem, SteemConnect, markdown syntax, maybe IPFS for file upload, etc. Then a lot of projects would come out of it.

Interacting with the chain is super easy as as it is already, but building something usable and decent enough for release is much harder for small teams because of the little details.
