While I have no issue with the overall change, I'm a bit confused as to what belongs where.
Philosophy of science, for example, should it go in Science & Technology or Military & Humanities?
What about work in the social sciences? Should a study in economics be posted in News and Politics, because economics tends to attract political attention; or Science and Technology, given that it's an academic study in the sciences?
Perhaps more commonly take, say, a thread about Marxism. It is, pretty intrinsically, political but it's also a discussion of one of the most prominent philosophers of the past few hundred years. E.g., the Left Reading group thread is currently in N&P, but it seems arguable that a thread specifically about reading philosophical works is perhaps better suited to the humanities subforum?
Military and Humanities seems to be almost entirely military and alt-history stuff at present as well.
