The walkscore widget flew through the transit and planning blogosphere in about July of last year. There's even an evil twin called drive score which Transit Miami covered in January. Now that gas prices are high, its getting some attention in the larger progressive blogosphere. This might show a tipping point in the transit and planning discussion whereas it becomes more a part of people's consciousness. It's on Barack Obama's mind at least.
Oh, and my score is 92. I'm not sure what else I need to get 100, but there is no bonus for transit. Since BART is a half mile walk and the J-Church streetcar is half a block away I think I might have a higher score.
