If "SU doesn't do software recomendation questions", how come we have the https://superuser.com/questions/tagged/software-rec tag, with 1,517 questions with up to 95 upvotes?
Here are a couple of reasons to pick from:
Not every question that deserves the tag deserves to be closed.
Having a common tag for questions that fit into this problematic category is helpful during cleanups.
Removing the tag does not remove the problem.
Secretly everybody loves a good software-rec question.
