Lately I've been noticing a number of questions being closed under the "Not Constructive" criteria. Some of these are clearly very constructive, in the sense of containing, as answers, useful tips and knowledge that people can use to do constructive things. I understand there is a reason to close questions that cause emotional or highly subjective responses, but in these cases, the question can only be seen as generating useful, objective and non-emotional responses. In fact, in most of the cases I've seen, the answers have all been exactly that.
For reference, the text of the "Not Constructive" reason:
We expect answers to generally involve facts, references, or specific expertise; this question will likely solicit opinion, debate, arguments, polling, or extended discussion.
Here is an example of a closure I can't understand: https://stackoverflow.com/q/826208/240633
Although the title seems to indicate some sort of Vim jihad, the questioner is simply asking for ways to use vim keybindings in other tools. To me, this is perfectly reasonable and entirely "constructive". The only clauses that remotely applies to this question, that I can see, are possibly the "polling" or "extended discussion", but I don't see opinions being solicited so it's not a poll, and since answers are particular ways to do what the OP asks, I'm not sure how "extended discussion" applies either.
Another example: https://stackoverflow.com/q/95072/240633
Although I understand this is an open-ended question, and in some sense a poll, the answers are useful, and it devalues this site when such questions aren't allowed in some form. If the intent of "Not Constructive" is to disallow all poll-like questions, there is no place for a lot of useful answers.
I had another example - https://stackoverflow.com/questions/1295634/best-gvim-tricks-for-programming - but the question was deleted shortly after I posted a negative comment about the moderation. Google has a cache without my comment and before the moderation: http://webcache.googleusercontent.com/search?q=cache:FhiaICeRrooJ:stackoverflow.com/questions/1295634/best-gvim-tricks-for-programming+&cd=1&hl=en&ct=clnk&gl=us
