This question already has an answer here:
I noticed there are many sites where I saw a question being closed by Off Topic instead of, say, Unclear what you are asking. Others which would benefited from This question was closed due to a typographical error were closed by Questions seeking for debugging help ....
I'm not discussing whether those questions should be closed, because they were rightly closed but when I asked about the reasons, I was told that it was due to the limited amount of close options (edit: wait, i'm not talking about the close options inside of Off-Topic reason, but aout the limited number of 1st-level close options) Stack Exchange provided for the sites. But for many questions I read, the close reason was not quite understandable wrt the actual close reason (which I had to ask in the corresponding meta about).
Is there a way to make those close slots variable? Ultimately, only moderators would have access to them as they have today (Edit: or could they ask the staff for more 1st-level close options).
My reason: Closing should be useful for the users at first glance of why. Specially if the user is not well used to the site politics and is a slow-learner about how the site works.
I understand there is the subtext for reasons as off-topic, but this is about communication: it is not about how do you think you send it, but how does the user (in this case the OP and in second place interested users) perceives it.
Edit E.g.: If the user read Closed as Off-Topic at first glance in big bold letters when asking about an on-topic question (but somehow unfitting in other ways), or another main closure title which he perceives inappropriate wrt the involved question (even after shallowly reading the rules) they will feel at first glance the site owners or community does not understand their own rules (which is not the case; instead just a poor way of communicating).
Disclaimer: No. I always understood why MY questions were closed. In this case, I am the... second place interested user, trying to understand how a specific site worked, and what and how was a question permitted in such site.
