I think this post touches on an interesting point about web development (might apply to other areas too, but the web seems particularly bad). A lot of things appear to be easy (Rails, Django, Heroku, AWS, JQuery etc.), but the number of different components you need to manage is still overwhelming. Furthermore, you often end up having to develop a low-level understanding of problems that someone else claimed to have solved for you. While this low-level knowledge is useful, it does add significant amounts of complexity for beginners and people who might not be committed as the hardcore full timers out there.

As we seem to push more and more for the "everybody should learn how to code" mindset, I think there is a big opportunity for someone out there to combined managed and protected environments with the ability to write your own code. I don't know if the solution is unifying languages across front and back end or a better set of abstractions, but I see way too many obstacles for 'simple' coding (although the situation today is without a doubt better than ever), and I imagine this is some of what the author of this post ran into.
