I think what set me off was certain statements that he was coming from a position of authority, like that he was a language design guy. At the same time, he didn't give any statements to back up how deeply he's researched the issues. For example, there's no discussion of C's fenv.h, or how fortran's IEEE intrinsics work. Add to that the jabs on the age of the specification, and it just ended up giving the feeling of being a much more shallow piece than it could have been; it just felt like he was saying, "I don't know what to do. Internet, decide for me."
