Care2.com (green social networking site) profiled on Mashable
Did you get a chance to look at the massive list of 100 plus green living sites profiled recently on Mashable.
They cover the gamut from charity sites to conservation, carbon calculators, shopping, search engines, green video sites, and lots more.
Do check it out, the list is quite comprehensive. I found a few i had not heard of before, including Segway Social, a community for Segway users.
