Weather 2.0

Cumul.us is a new website that uses the “wisdom of crowds” in order to to predict the weather. Aggregating weather data from openly available sources and APIs from AccuWeather, Geonames, Google, NOAA, WeatherBug and weather.com, the weather predictions are likely to actually be more accurate than if you were to use just a single forecast. Along with with the weather predictions, you can participate in the community by trying to predict the weather yourself, as well as submitting what you’re going to wear. You can check out what other people are reporting they’re going to wear, too. As you make your predictions, cumul.us goes to the available weather data sources and saves what it was really like that day; then your prediction is scored for accuracy for the conditions and/or temperature. The better your predictions, the higher your user rating. The site’s content floats in fluffy white clouds on a blue background, making this fun web 2.0 “wisdom of the clouds” community worth checking out.
