[V2] change /api/articles/feed to /api/feed

[eandre]

In the current API spec the routes /api/articles/feed and /api/articles/:slug are ambiguous, in the sense that they use the same path structure. This is a problem for two reasons.

First of all, it makes certain API routes unusable (such as the excellent https://github.com/julienschmidt/httprouter for Go), because the internal trie structure does not lend itself to making this distinction very well.

But perhaps more importantly, it breaks the user experience in a weird way. If you try to view an article with the title Feed, it will have a slug feed and try to look up /api/articles/feed and break, because that returns a list of articles instead of a single article. Overall it becomes an edge case that you have to handle everywhere, in both tools and business logic.

Might I suggest /api/feed instead? It's unambiguous and equally clear!

Great idea.
Closing it as it's now tracked with #713 for a complete review of existing endpoints.
