Cumul.us - Wisdom of Clouds

Cumul.us uses the idea of the wisdom of the crowd to bring you the weather in a new way. They aggregate from a couple news sources to get your city's forecast, and they let you make predictions as to what the weather will be like in the future. The more often your predictions are close to the actual numbers, the higher your rating goes so that people know to trust your weather predictions in the future. Often it's hard to determine what you're going to wear, but if you check out cumul.us, you can see what other people in your area are planning on wearing, and you can dress accordingly. They display the most popular choices for what people are wearing on top, bottom, and as accessories via ShopStyle. Instead of depending on what the local forecaster has predicted, why don't you get a crowd's prediction from cumul.us.

"cumul.us is a place to get simple, accurate, and useful weather information.

What makes it simple and accurate is that it collects weather forecasts from several sources and combines them together to give you a more accurate average, using the idea of the "wisdom of crowds". In short, cumul.us is the "wisdom of clouds". Not only is there data from meteorological sources, but people can make predictions themselves.

What makes it useful is that it gives you the information you really use the weather for every day, like figuring out what you should wear. Using the aggregated weather data (and other people submitting what they are wearing) it will suggest what you should wear."

Everyday people check some source for their weather info, and if they can check out that info while seeing what other people are going to be wearing, their decisions on what to wear and what to bring with them for the day will take a lot less time and have a lot more of a chance to be accurate. ShopStyle and other clothing stores will make for easy advertisers.

Why should people trust random people's opinions on what the weather will be like instead of the forecaster who has tools and radars at their disposal to make the most accurate weather prediction that they can? Will people go to a page to make weather predictions and see what people will be wearing that day, or will they just get the brief forecast from their current news source?
