I know, the nerve of me posting in LCF. But there was a brief article in BusinessWeek about a woman from Zipcars that started a new site. It's called Goloco. It's a "service that helps people quickly arrange to share rides between friends, neighbors, and colleagues."
I thought this might be of interest here in LCF, as it seems like the kind of site that would help those that are hanging on to cars for the most infrequent of trips to finally cut it loose. Likewise, if you are totally car-free, but do require a ride once in a while, it could be useful. I'll probably blog about it later too.
Or you could just throw me down the well.
