By this point I highly recommend actually writing some code to solidify your Clojure knowledge if you haven't started already.
While I will be among the quickest to acknowledge that there is great value to be gained by typing in example code, without structured exercises, the article might be providing a fine tutorial or feature list or cookbook, but it is not a course.
Courses look more like "Learn Python the Hard Way" than blog entries. They're hard to make and one for Clojure is sorely needed. The easy parts of Clojure are the syntax and the common idioms. That's why Lisps have a long history as introductory programming languages. The hard part is learning to apply them to the sort of hard problems that one applies other programming languages to.
All that to say, that there's nothing wrong with the article as an article. In fact I think it represents an admirable amount of work for a positive purpose. My only criticism is that it is not what it says it is, and the only reason that is a criticism is that it claims to do heavy lifting which it does not.
