Oh - OO is pretty vaguely defined; I'm talking specifically about C++/Java-style class-based OO. (I haven't ever used CLOS-style OO, and prototype-based OO is probably vulnerable to the same pitfalls as class-based.) Also, while this article by Clay Shirky (http://www.shirky.com/writings/ontology_overrated.html http://www.shirky.com/writings/ontology_overrated.html) is more about categorizing information, it demonstrates very nicely why trying to pigeonhole everything into a hierarchy of classes doesn't always work in practice. (I posted it to the front page, since it hasn't been yet...)
