URLs in RSS feeds wrongly assume that all top-level posts are questions
With the recently added article post type (used to share recipes on Cooking), the URL to the post is
nnnnn is the post ID), or
/ar instead of
/articles for shorter links.
However, the category feed still uses
/questions/nnnnn as the URL for each post.
The result is that the link shown in one's feed reader returns a "404 Not Found" error page when followed.
The category feeds should take the post type into consideration when generating the URL to the post, so that the link shown in the feed reader successfully takes the user to the post in question. (Assuming of course that it is still available.)
