Bike maps social
The GroupLens team at the University of Minnesota has a new project, or at least one I just noticed: Cyclopath. This is a map of the Twin Cities with a social ability to mark blocks of the city with regard to their bikeability (potholes, hills, traffic, etc.). You can give it two addresses, describe your preferences (I like bikepaths and bikeroutes, but dislike hills), and it will find a route for you. After trying it out you can grade the route and leave comments for future cyclists. Very cool. If you bike around the Twin Cities you should check it out and get an account. Too bad they don’t let you save or share routes.
