A draft of this blog post was on Hacker News a couple of days ago (<a href="https://news.ycombinator.com/item?id=9640367" rel="nofollow">https://news.ycombinator.com/item?id=9640367</a>) but the discussion ended up mostly being about the fact that it was a draft that wasn't intended for wide distribution.<p>In contrast, this is the final version and it <i>is</i> intended for wide distribution. So please, discuss away! :)
