Now, to their credit, their definitions of the major convention types aren't too badly off. They get some things right. They even list "literary" conventions (which in this case includes all sorts of what I'd call general cons like BayCon, etc., not just specialist events like Potlatch) first. But otherwise, I feel like I've been defined off to the fringes of the field and been told that written science fiction and its related interests are a minor, irrelevant interest compared to Real Science Fiction, which consists of watching television and movies.
I feel old.
