Let's raise the tagging topic to a new level of meta-ness by talking about tags on meta!
We have four different tags on meta.SFF which are about question closure:
closed-questions (81 questions): "For questions about closing questions, or about a specific closed question."
close-reasons (58 questions): "For use when discussing the principles and reasoning behind closing questions."
vote-to-close (31 questions): no tag wiki
closing (7 questions): no tag wiki
What's the difference in meaning and usage, if any, between these four tags? Should they be synonymised or merged together?
