What would interest me is an implementation that allows you to plug in different weather backends, so that having an API key to worldweatheronline, or screen-scraping weather underground, or building a bridge to your serial-port connected weather station all can target the same interface; to provide current conditions/historical conditions, a forecast, etc.
Are there standards for this, or is it mostly ad-hoc, the whim of the sites or commercial services which aggregate information and provide forecasts?
So it certainly could be done. And I actually looked into this a few years ago, but it wasn't trivial enough to make it worth the time back then.
I know very little about this space, but when you suggest screen scraping WU, are you implying that they have no API or XML feed or some kind of open feed of their data ?
That's disappointing. I always assumed they did ...
If you're open to bug reports/feature requests:
* The image for clear weather is a bright sun, which is a little odd to see in the 'Night' column
* Many city names are duplicates. How do I know I've got the right one?
It gets me the information for the forecast and current conditions quickly and painlessly. I have used it for years. I much rather have the NOAA forecast and current conditions to anything else.
This would compliment weather for me.
On another note, was it really necessary to add the bit about the NSA? Hasn't that been played to death now?
Next thing someone will have the bright idea of transmitting data as sounds over VOIP services, and we can start setting up BBSes on skype...
