I came to this question <https://stackoverflow.com/questions/16732647/convert-rtf-file-to-pdf-file/16734426> that was closed as not constructive.

The reasoning for closing it are not 100% clear to me, but there is enough discussion about this topic ([Help us make "Not Constructive" and "Not a Real Question" closures more effective](https://meta.stackexchange.com/questions/171732/help-us-make-not-constructive-and-not-a-real-question-closures-more-effectiv)). 

The way I think about it, the question doesn't fall to the shoping list category since it is not asking for the best way to do what hi wants (RTF->PDF) but any way that conforms to his limitations (open+pure java). Maybe it is not a good fit for stackoverflow, but it looks like a good fit for programmers.stackexchange. 

Would it be a good idea when closing a question from one site to migrate it to another if it's a perfect fit for it?
