I see many AskUbuntu questions that are really too localized for the format. That's a recognized problem: we do
have a too localized
flag, after all.
But I think many localized questions are worth answering at a broader level. For example, this problem is specific to the present state of an unstable PPA for a certain software configuration; it's very localized. But the greater question—'What should I do when a PPA breaks my system'—is quite useful.
Could we possibly get a feature similar to the duplicate system, but one that links closed questions to their more general equivalents?
