It's a bit of a slow weather day, so I thought I'd share with you today a few of the more interesting inquiries I've gotten during my 20 years working with Weather Underground. I responded to all of the emails, but not the phone calls. Enjoy!

Back when I helped found the world's first commercial on-line weather service--The Weather Underground--back in 1995, we adopted a simple and colorful rainbow logo that expressed our mission well: a website dedicated to unlocking and sharing vast amounts of weather data with as many people as possible using the latest digital technologies, in a way that is visually appealing and engaging. Nineteen years later, we are transitioning to a completely new logo, as part o...
