Half the answers are helpful
Your questions (the one here and the one on StackOverflow) generated no answers, but comments. It's good that some of the comments were helpful, but comments don't follow the same quality guidelines as answers. For example, there are no down votes on comments, so you can't really say if the community disagrees with a comment.
the other half think the topic isn't constructive.
Unfortunately, regardless of how interesting your question may be, it doesn't have a single answer, and those kind of questions often lead to lengthy debates. We can't really safely measure a technology's popularity, your question is asking for opinions rather than experiences and facts. The pointers you got in the comments are valuable, but there's no objective way of judging them.
Adding to that, it's also too localized, as @ThomasOwens explained.
Make sure you read the faq and the Good Subjective, Bad Subjective blog post that is linked to the close notification and always keep in mind that "not constructive" is Stack Exchange lingo, it refers to how your question measures up to those guidelines. It's not a comment on the actual quality of your question.
And you can always try asking around in chat. Same crowd there, and your question is interesting enough to start a discussion (I hope). Of course the discussion will probably be more casual.
As a sidenote: Avoid cross posting. If your question was closed on StackOverflow, chances are it will get closed here as well. Otherwise it would have been migrated instead of getting closed.
