Really nice article. While I'd quibble about some of the details, this categorization of comments is really good. Really good discussion around each category too. Not sure if is a separate category or not, but I often do Quirks type comments especially when dealing with APIs of libraries with links to relevant documentation ( even if though those links may go dead at some point, I'll capture the essence of the quirk in the comment and leave the link )
