Please read a few of tutorials from my blog. Most programmers in your situation told me that they had no problems following it; it only gradually introduces advanced Clojure concepts, and code snippets are usually extremely short + completely executable interactively as-is.
This is a great site. A few pieces of unsolicited feedback from a marketing perspective:
* Always have the call to action repeated at the bottom of the page; you did a great job having it above the fold, but I got to the end and had to scroll back up to express intent. That's a flowbreaking design.
* This is purely stylistic, but I strongly prefer the first letter of each line to be capitalized. I find the stylistic inconsistency around capitalization offputting.
* You have pretty nicely made docs, consider making the link to view the sample chapters a clickable picture of the first diagram-page in your chapter.
Thanks! I have this slated in my to-do tabs (which I actually do lol). Just looking through it looks like you did a lot of work and took a lot of time for this so just wanted to say thanks.
