I disagree with Braiam slightly in the closing paragraph:
closing questions is not bad for anyone
Pushing antique questions into the close queue means you're using another four votes from the active reviewers to deal with something that isn't really an issue any more.
If we had infinite numbers of reviewers, I wouldn't care as much but we get more new questions every day than we deal with. A number of these aren't even getting the review they need. This suggests that too many people are loitering in review and not on the /questions/ page.
If that carries on too long, we stop being a viable site.
PS. The reason for your example entering the close queue was it gained a new answer (which was probably part of the first-post queue). In instances like that I can understand why something might get reviewed in full.
But that said, I don't see what's particularly evil about this question. With its edit, it practically meets even the softwarerecs.SE definition of a good software recomendation question. It's the answers that need improving.
