I read it all for the express purpose of reporting my reading time to you guys (to contribute to the thread).

Reading fairly carefully and stopping to think wherever I wanted to (though by the end I was being less attentive) it was 20 minutes of very solid reading. That is a long time to read an article.

I think hexane's TL;DR is fine. I don't think everyone should feel like reading this whole article is the best use of their time.
