In my close vote queue, I sometimes get questions on high-level quantum mechanics or general relativity that I don't know enough to judge. This is annoying to me personally but on a larger scale, it may cause problems as people who are not very familiar with a subject may vote to close before going through it.
Hence, I propose that we get the ability to close vote questions with certain tags only after getting some amount of points from answering and asking questions related to that tag.
