Great job. As you said, the steem.js documentation just list the methods we can use. It's great to see someone improving that documentation. Explaining what the method does, what parameters it takes and what the result of calling that method will be will be great. I think I've seen streamOperations method explained somewhere else but all the other are new to me. I think steem.js has a few examples on github. It will be great to see some additions in that folder too.
