He's wrong when he says that Medium uses a 22pt font. They have a 22 PIXEL font. 22px is much smaller than 22pt. (37signals' blog and Zen Habits also have a 20-something pixel font size, not 20-something points).
Otherwise, this was a pretty decent overview. A lot of programming-focused sites ignore good practices about line lengths and font size.
