Yeah, for the weather thing, you have to sign up for the Weather.com XML feed [link] that sends you a couple of IDs you need to stick in the skin (it just appends to the usual link you use to get the weather for a certain area), the email they send with it provides an example layout for it, you basically use that.
I'm certain it's the website. I accessed it earlier to see where the data was collected from. It's totally different now and says something about an error. It worked before and there was a whole lot of data on the same page.
