How is it not one of the better questions on SO? It's educational, it's on-topic, it's more cerebral than the usual questions about jQuery, it has high quality answers, the question itself is as clear as day, it's interesting, and it's very popular in terms of views and upvotes.

There's a degree of opinion in most answers anyway especially as there's often multiple ways to do the same thing and every answerer will have a preference of some kind. I don't necessarily see this one as a particularly subjective discussion anyway, or why you think I'm trying to make SO be something it's not. In any event, why are marginally subjective discussions are a horrible thing anyway in a Q&A site?
