Oh I am too, no worries about me judging your code lol. SteemPress's code is in no way "good" at the moment, it's got some massive functions in it that really need some love. But that's what prototyping is for!
And sure, I'd be more than happy to share some code snippets on how I used fguillot/json-rpc to access the API. Maybe that's an idea for a blog post in #PHP :)
