PWSweather is co-sponsored by WeatherForYou.com and HAMweather. WeatherForYou.com maintains the program, includes the data with local forecasts and offers items contributors can use to display their data on their own web sites and share with other web sites. HAMweather provides programming expertise. Both entities share the cost of servers, bandwidth and other expenses associated with the program.
The program was started in 1999 on WeatherForYou.com to demonstrate the contributions of personal weather stations by including the data with local forecasts (along with credit and link to the contributor), provide a central place where personal weather station data could be shared among users and encourage people to install more stations. It was expanded to PWSweather.com where archives of the data could be accessed and the data displayed on graphs a few years ago.
Data is available for use by contributors in standard METAR format along with XML. Also included is METAR and RAWS data. Many software programs can access the feed to create regional weather maps and outlooks. The data is also available to anyone who wants to write other scripts and programs to utilize the data.
All services to contributors are provided free of charge. We're currently researching other things we can offer. There's a couple threads related to that in this forum that I'd encourage you to contribute to.
There's no reason you can't participate in multiple programs. I would encourage you to participate in WU, WeatherBug and CWOP along with PWSweather.com.
HAMweather did become a part of WeatherNation a few years ago, however their participation in PWSweather has not changed.
Hope this answers your questions. If you have more, ask away.
