This is a toy project I'm working on at the moment.

My app contains questions with multiple choice answers.

The question url is in the following format, with GET & POST mapping to different actions on the questions controller.

GET:   url.com/questions/:category/:difficulty      => 'ask'
POST:  url.com/questions/:category/:difficulty      => 'answer'

I'm wondering if it's worth redesigning this into a RESTful style. I know I'd need to introduce answers as a resource, but I'm struggling to think of a url that would look natural for answering that question.

Would a redesign be worthwhile? How would you go about structuring the urls?
