I actually agree with you, if done well I think that coding questions are fun too. At the same time, I also happen to know a lot of very strong developers who hate them. I think the reasons vary, but some are called out in the article (lack of a familiar environment/IDE, the contrived nature of questions). The answer to a coding question is also impossible to "fake", at the end of the day you get it or you don't (whereas some situational/behavior questions have more of a fudge factor).

Whether you hate 'em or love 'em, the main point of the post is to advocate approaching coding questions with a strategy that you've practiced and can repeat over and over again.
