I only skimmed the article until I saw "lein new", so I have no comment on anything before that. But I did want to say that I liked the explanation of the tree structure with the English language example. I think I might steal it. With the respect to framing the article (or others like it you might write in the future) I wonder if you might be able to find a rhetorical strategy that responds to nicolethenerds' criticisms by writing for a specific person who is also a woman rather than groups like Women Who Code. As long as it was somehow clear that it was indeed a woman that you were writing for (I hope you have a female friend who is curious about Clojure!), you might be able to satisfy your three intentions.

Necessary disclaimer: I am a guy and I have no expertise. I am just thinking out loud.
