Under what circumstances would it be appropriate to close a question as "too localised" on MSO? Unlike the other sites, the purpose of meta is to provide support rather than build a QA database, so I don't see how a meta question being localised is a problem.
I'd love to have some data related to the close reasons, however it's not available yet. So, subjectively speaking, most of the time on Meta, questions are closed as duplicates (mostly), off-topic, or noise/pointless.
Too Localized is mostly used to clean up questions that are no longer relevant (invoking the "specific moment in time" clause of the close reason) -- see this question.
This is pretty much a housecleaning activity (with the ultimate goal of deletion most of the time). This would apply to posts such as:
Note: localized bug reports (where no one can repro) are the exception to this -- these should be mod-tagged
The first topic that jumps to mind is gay horses.
Other reasons are for questions about specific questions, users and answers on SO, rather than about the rules and policies of the system in general.
It’s funny that there’s a question in the sidebar claiming the opposite problem, that meta questions are more vulnerable to the effects of time.
