He lost me as soon as I got to the part where it became apparent that he didn’t understand what condensed and extended typefaces were. Consistently misusing the word font was another strike against him.
He said that mixed case words were easier to read than either upper or lowercase, then justified it by citing a study about street signs. A study on street signs isn’t much evidence for drawing any conclusions about readability other than on street signs. He equated blackletter typefaces (but didn’t seem to understand that Fraktur was only one style of blackletter) with the Nazis — well maybe in Germany. Here in the U.S., there’s more of an association with beer labels, Oktoberfest and cheesy typography on motorcycle gang jackets. Many of the characteristics he assigned to various faces were just his reactions, which don’t match up at all to mine.
And what’s that thing he mentioned about brain network nodes? Last I checked there’s no such thing, but maybe he was speaking metaphorically. I think his explanations went a little too far in breaking down things in ways that resulted in a mumbo jumbo mix of his own ideas and accepted wisdom.
I mostly agree with most of what he wrote, but sort of rolled my eyes at other things. It all boils down to this guy’s take on things. I’m just not seeing him as much of an expert — just a guy who’s thought about it enough to have some opinions.
