It's a very interesting question, and I'm a bit disappointed we couldn't find a way to keep it constructive.
Minutes after the question was posted, one of our most senior members (by reputation) detected its not constructive nature and flagged it, asking for the "insufficient explanation" post notice (that's still visible on the question). I saw the flag seconds later, while examining the question and debating whether I should close it or not. I decided to add the post notice, hoping answerers would take it into consideration and not just answer for the sake of answering.
Few hours later I checked back, read the five or six answers that were posted at the time, and again hovered over the close button. There were a couple of answers that completely missed the point of the question, and the whole thread was starting to feel like a typical not constructive one. Again, I didn't close it, as the two technically inaccurate answers were getting downvotes and polite comments explaining what was wrong with them, and I was hoping the answerers would get the point. And they did, and removed their answers.
So, I checked back a third time, there were no flags, only one close vote, three good answers and a great one. At the time it seemed that we had salvaged the question, and decided to share it around, as I typically do with all questions I find extremely interesting. And it exploded, 14.4K views, 20 answers (+3 deleted ones). Unfortunately the later answers are quite poor (imho) and repetitive, I have no idea why people kept answering a question that was already sufficiently answered (again, imho), but they did.
Perhaps I should have closed the question right when I first saw it (minutes after it was posted), or when the flag asking for the post notice appeared (it was a good hint that someone else thought the question was attractive to poor answers). My spider sense was tingling every time I checked back, but until the last time (when the question was already closed), there seemed to be good reasons to let it open for at least a while more, and since there were no flags and I only spotted a single close vote, I happily reverted to user mode for this one instead of dropping the mod hammer.
But right now, the question has more poor answers than good ones, and lots of off topic(ish) discussion in comments. We didn't really manage to pull this one off, and I probably should have protected answerers from wasting their time by closing the question early on. We can theorize for hours on how the question could work, but in practice it didn't and it did generate debate, arguments, polling, and extended discussion.
There might be ways to accommodate and protect such questions, but we haven't found them yet. Yes, the question is extremely interesting, and perhaps on a different day it might have attracted a whole different crowd and a very limited set of amazing answers, but right now it's a typical not constructive thread, with tons of off topic / not constructive elements in answers and in comments. Shame it turned into a crapfest, but it did, and unfortunately I can't think of anything we could do to salvage it now.
