Josh Sundquist, CNN Hero

CNN recently profiled Josh Sundquist, creator of the online amputee network "Less than Four," or <4. The website provides a place for amputees to meet, talk about their prostheses or other interests, and create a blog about themselves. According to CNN, it has over 200 members and 10,000 viewers, but judging by the number of calls we've received from people who saw the clip, it might have many more soon.
