Well, seemingly the weather binding (I’ve never really used it) is using the ‘proper’ Yahoo API for weather data. The method that the demo and I use is simply based on the HTTP binding and parses an RSS feed (see the new URL in my initial post).
So, the weather binding may need oAuth support in the future, and the HTTP binding method can still be used, just with an updated URL.
I hope this helps to clarify.
