Sense of Community is the key

One of my friends was participating in the CHI 2006 student contest on making ppl healthy. I kept pointing that sense of community is the key in helping ppl watch their diet & weight and technology should help them get that done instead of being overly intrusive. I was suggesting a version of Y! games where ppl wud be able to compete during their workouts. Here is an article on USA Today reporting new treadmills, stairmasters and gym equipment connecting to internet allowing people to compete with others. I am keen on seeing this succeed.
