I'm reacting to two things: 1) People who say that categories are strictly "is a", and something belongs in a category only if it is an example of that category, and 2) People who say an article or category cannot belong to too many categories.
Just weighing in with my own opinions here.
1) "categories are strictly 'is a'" is too narrow a view and precludes us from doing many interesting things that we could and should be doing
2) While there may be some reasons from a technical or aesthetic point of view to limit the number of categories to which any particular article belongs, I can't see any need for a hard-and-fast rule. Probably good standards will evolve over time as we use categories and learn some things about them.
