It was at this point I realized the entire premise of the article was a very long-winded way of saying "I like using high DPI monitors when I code". And then tossing in a bunch of technical details to make it sound like a "fact".

More like "I like looking at really smoothly rendered TTF fonts".

I've tried to use TTF fonts in terminal. None of them work well enough, or renders better than the classic 6x13.

Indeed. (Especially given the fact that two characters have 14 pixels in them.)

IIRC, I have fewer fingers than that.

Yes, but you have more fingers and toes than that!
