Kind of like Twitter for the amateur meteorology crowd, cumul.us uses crowd sourcing to answer two simple questions: what’s the weather like and what should I wear? The site supplements “official” weather conditions with user input about your location– internationally, even (Ljubljana, even). Schematicians in Los Angeles may find the tedium of “It’s beautiful out and wear whatever you want” unbearable, but for the rest of us, this could be kind of useful. Fun, at the very least.
