I think the point isn't who closed it, but the fact that this type of knee-jerk reaction is fostered within the community at SO. I see, time and time again, questions that are closed as off-topic because it's not a "1+1=X" problem/solution, even though there is much value to be gained -- within the programmer community -- of the question being asked, and the responses that are given.

If I have a problem that I can't reproduce but is related to programming, and there's a chance that someone else has also had a similar problem and found the solution, SO does not offer a way for me to connect with that person.

On the other hand, if an unreproducible problem is posted and allowed, and multiple answers are given, there's a good chance one of those will point the OP in the right direction, and in turn, someone else that faces that same issue. There should be nothing wrong with this type of interaction. If someone feels it's a waste of their time, by all means, move on.

I know this has been argued ad nauseam, both here and on meta, and is likely something that will never change, but that's not the point of my post here. I just think it's worth defending the stance that the SO community is too quick to close programming related topics that may not be completely black and white.

By the way, programmers.stackexchange.com also suffers from this same fate, and I don't think this question would have received a much different response there, even though it's supposed to allow more open-ended questions.
