I recently answered a question on WPSE that the author was kind enough to bundle as a plugin.
I realized that there was no way I would have gone through the trouble of answering this if that was not the case. It's often too much work just getting setup to answer a question.
So the idea behind WPSE-Question is that complex (or even easy) questions are able to be downloaded via a plugin the answerer can install. It is not meant to take away from pasting code into WSPE but rather complement it.
The problem is how would we encourage it's use.
