If the author is around here, could they explain their use of <blockquote>s? They appear to be used to introduce comments inside the text, but that’s really a confusing markup.
I believe it is a habit back from my journalistic days, when there were "insets" besides the main text with "things that deserve mentioning here, but kinda out of the main flow... but more related to it than footnotes." I miss the richness of markup of paper magazines!
Does it harm the reading experience significantly?
