From David Bernstein's excellent The Fredcast Podcast comes an interview with Ellen Hall from CatEye, the maker of lighting systems for you bike.
Ellen talks about the World Commute website, where people can enter data for their car and then daily keep track of the miles they rode, ran, biked, skated, or otherwise. The website will give users the amount of money and gas they've saved, carbon they've prevented from going into the environment, and more. There are plans to create social networking functions, the ability to create groups for friendly competition, and more. It's really a great resource and I look forward to entering some data into it so I can give it a thorough review later on!
Check it out now and see what you think - those of you who like to crunch numbers to see just how much you're saving will love this!
People, not speed.
