Earlier quoted context omitted.
As a mere reader and non-user of SO, does it matter if the question was closed? The answer's still there, googlable, and it still gets updated regularly, no?
It suggests that this is not the ideal sort of question for the site, and that any future attempts at similar questions may be met with greater resistance. Additionally, if the relevant information ever changes, no new answers can be submitted.
I'm not sure if that's the best way to do it, but it's an option.
