The question was deleted on 2010-11-24 by Diago♦. It had previously been locked (i.e., basically, made read-only — locking has nothing to do with closing) since 2010-08-05. (Only ♦moderators and ≥10k-rep users can see deleted questions.) I have no idea why the question was deleted. It can still be undeleted by a ♦moderator.
For the time being, the content is still available via the Google cache. When it goes, it will undoubtedly live on on one of the many sites that mirror SU (finally a use for them!). The question is in the data dumps produced before it was deleted.
