People come to StackOverflow because it has a good signal-to-noise ratio. Maintaining this ratio, and the reputation of the site as a resource rather than a discussion board is important.
I personally jump to StackOverflow results on Google pages because they almost always solve my problem exactly. If the results start being polluted by a bunch of less relevant discussions--which, being popular, are likely to rank well--I would probably stop using SO results as much.
On top of this, just leaving a question like this open hurts the question itself as well. There is no reason to want 100 different answers all pointing out the missing space in different words! That way lies madness and Quora--where many answers to popular "survey" questions only get read because of the follow feature and a Facebook-esque machine-learning-based feed.
