Wrongly closed (or wrongly open!) questions, on main or meta, are broken windows that mislead the whole community about what sorts of questions should and should not be closed. So even though this question is old, it's worth reopening.
While that meta question should never have been closed, the wording was harder to understand before izx's editizx's edit (which happened before the question was closed but probably after a few of the close votes). Maybe that's why people voted to close it.
