Personally, when I see a tab, sub or tag labeled "politics" then I assume it's an umbrella for all things related to politics. I understand what you're saying and it makes sense. However, I have the feeling that many users, especially if they are taking a look at the tags for the first time would likely think the politics tag is more general. I'm not saying that's "right" but might it not be easier for political theory and political philosophy articles to be tagged as such? I don't see how people would know without being told that #politics is for political theory and political philosophy, but then it's a topic that I read and post about less frequently than my other areas of interest as I have a fairly basic knowledge of it. I will admit that I have been using #politics in a way that you describe as incorrect. After reading your reply and thinking about it a bit, I think that most of what I have posted would definitely fall under #uspolitics or perhaps even #usgovernment.That's what I use it for, political philosophy and theory.
