We have used two of our three slots for reasons for closing questions as off topic.
We hadn't thought of any special reason back when the list was made for the first time, but I have the feeling that recently, I have been closing quite a few culinary-uses questions.
It seems to be that this can be a very good candidate for the third slot:
- It is needed relatively frequently.
- It is quite surprising for new users that we have such a policy. Not only for people completely new to the network; users with a decent amount of reputation on other sites seem to not notice that this is, essentially, a poll question. So, users who have spent enough time around to cast a flag will see the reason on the list and learn of it before they have made the mistake of asking such a question themselves, which brings them through the unpleasant experience of having a question closed.
- We will still get such questions, especially by brand new users who have never cast a flag. In this case, having this as a "canned" text looks more official to them and less like a tyrant's whim. We seldom have questions closed by five users, typically it is done by a moderator, so it can look quite one-sided, especially when the reason sounds so strange to the OP that he doesn't believe it can be a rule.
I wrote a suggestion for the new text; if you agree with it, upvote. Any suggested edits to it are very welcome!
If anybody has arguments against creating the new reason, please leave an answer too.
