Over the last couple of weeks, I have found myself wondering about the closure (or near-closure) of some questions on Meta. All of these questions were closed as "not constructive". And in each instance I thought "what exactly isn't constructive about this question?". Especially within the context of Meta. 

Some recent examples of what I'm referring to are:

- http://meta.stackoverflow.com/questions/170678/does-the-tag-system-need-revamping (3 votes so far)
- http://meta.stackoverflow.com/questions/170827/where-can-i-find-out-more-about-the-process-of-tag-cleanup-on-a-stack-exchange-s (3 votes so far)
- http://meta.stackoverflow.com/questions/170188/what-is-done-to-extend-outreach-to-other-countries-and-yes-women (closed and even 2 votes to delete)
- http://meta.stackoverflow.com/questions/170849/what-do-you-think-of-this-suggested-edit (4 such votes so far)

And I remember commenting on a couple of others. I'm not suggesting that this is a recent change on Meta. Perhaps nothing changed at all. It is merely something I noticed and paid attention to. 

To be honest, I just don't get it. Not all of the questions are great, some have content I disagree with (and I have left comments indicating that), but I don't see how they are "not constructive". Especially on Meta, where discussion is allowed and welcomed (if on-topic). 

So my questions are:

 - What makes these posts "not constructive"?
 - Should these really be closed? Or put in another way, what is the problem in leaving them opened?
 - Are we perhaps using this reason to replace/create a close reason we're missing?
 - Do we use it to indicate a question/discussion has "run its course"?
 - Are we perhaps using it to indicate disagreement? 

I would love to hear your thoughts. I have been called out for close votes before which were misinterpreted, so who knows what I'm overlooking in this instance.

For reference, and for those who can't close - the Meta description for `not constructive`:
