The Open Weather map project is an open data source for weather data. http://openweathermap.org/ To quote the website: OpenWeatherMap is startup that offers free current weather data, forecasts and history data to the developers of web-services and mobile applications. As a data source it uses official meteorological broadcast services, raw data from airports weather stations, raw data from radars, and raw data from official weather stations. All data are processed by unique mathematical algorithms that can provide precise online weather forecast data flow and different weather maps like clouds and precipitations. On above of that the service is focused on social aspect by involving owners of weather stations to connect them to the service to let weather data be more accurate. The concept of OpenWeatherMap is to make weather data extremely accurate and free. By analogy with OpenStreetMap that make geographic information be public the OpenWeatherMap make weather data be public. It seems this would be a better fit than the current way things are done... How tightly coupled is weather.com into this plugin?

I have visited the homepage of the project, and even read some the source code of the plugin. I don't understand how my bug report is invalid - do you mean that this will not be implemented in this plugin?
The plugin doesn't use weather.com. The homepage tells you it uses api.met.no/yr.no, the rest is written in TODO and README (see http://git.xfce.org/panel-plugins/xfce4-weather-plugin for up-to-date versions).
