Agree with most of his points. Unknowingly, my blog has followed the same kind of timeline. My current design is not quite minimal, but the content has nothing on the side, I don't have a huge header with a calendar and god knows what else. The worst thing I have is a single ad in the header, but this actually works quite well for content because usually the beginning of content will be at the upper-middle of your screen, where the eye is usually resting..

The one thing I disagree with is comments. Comments are hard to get right, but they're not replaceable by social media alone.
