Yeah, I didn't find those two categories too intelligent back when the article was posted. I also have to agree, to a degree, with Panda about the contradiction in the first category. "A person who simply enjoys anime." belongs to the definition of an anime fan, not an otaku. Somebody who simply enjoys something doesn't go out of his way to methodically hate some detail about it.

Still, it's good to remember that the more you like any aspect of a show, the more you will enjoy it, be it a style, a character, or anything else. Thus being able to make a big deal out of them is a good thing. You get more out of the time invested than somebody who stoically watches through the whole thing without as much as raising an eyebrow. But I don't necessarily see this as an otaku exclusive trait, nor does it need to be so negative that it makes you hate shows that lack the particular traits you normally enjoy the most.
