I think it is related in a 'practice what you preach' way. If the article is about readability, and the font it is written in is not readable for a large portion of the population, I think it is valid for somebody to open the discussion on that. At the same time, I didn't have a problem or notice a problem reading the posts text. Looking back, it is a bit on the small side though not uncommon.
