It's well written and easy to understand, and I like the format of the code samples. However, the topic bugs me slightly - "Why XXX is problematic" is a completely milked out topic, just like "Why XXX is better than YYY", "XXX is Awesome", etc. Although your writing isn't bad, I prefer to read about new ideas, not criticisms of already-existing products (although criticisms well deserved in some cases). Don't take this too personally, of course - writing about new things is much harder, and even writing about things which may have not been summarized as concisely or not been put in your words is good practice.
