To fill an obvious hole, walkscore.com is expanding into the wheeled domain. The site is still in development so people are asked to contribute and vote on factors that should be included in a place’s bikescore.
The site requires users to sign in with their email address and then users are given 10 votes to distribute according to their preferences. Also, users can contribute their own ideas for others to vote on.
So head on over there and vote early and often! (if you use multiple email addresses- but you didn’t hear that from me…)
