I recently closed the above question. The OP, quite politely (thank you!) challenged my closure. My explanation quickly outgrew a comment, so I will use this space to address the OP's points:
I think it was a bit over-eager to use a mod vote to close this question and then engage debate.
It was a calculated move. :)
I honestly debated whether to close it, whether to simply comment, or whether to do nothing. And I chose the course which I thought was the most likely to solicit (healthy, hopefully!) debate on the issue.
The question is clear and has verifiable answers, it is not a duplicate, it is not unclear, it is not too broad and it is not opinion-based.
I grant you each of those points. It is not a "bad subjective" question. It could, in theory, be somewhat open ended, as there could, again--theoretically--be multiple correct answers. Although I suspect the list of correct answers is quite small, and not likely to expand by much even over the coming years.
Also I think it would be of interest to others.
Possibly. Although I suspect it's not likely to be of great interest to many people studying the Spanish language. It's really more of a computer science question, than a Language question.
Nothing in the public on-topic discussion suggests it as unsuitable.
That's true--it's not spelled out as explicitly off-topic, but it's also not spelled out as explicitly on-topic either. And one of our close reasons is for "learning resources" which are off topic (and ought to be added to the help center text!)
I felt that, categorically, this question was closest to "learning resource" than to any other category of on- or off-topic question we have enumerated. This is ultimately why I closed it--I felt it was in the spirit of our on/off-topic reasons, although admittedly it isn't within the letter of them
@Flimzy, since you seemingly admit that closing might be debatable, would it not be more reasonable to allow it to be voted closed rather than using a unilateral mod vote? Anyways, my 2c. :)
Again, it was a calculated move, in an effort to get the community engaged.
These are my thoughts. What say the community?
There's no rule that resource questions must remain off-topic, if the community wants to make them on-topic again.
