Well I might be using the term a bit loosely. Some people would call skateboarding, longboarding, or snowboarding an extreme sport, while others would say it's skydiving, or mountain climbing with no ropes. I just figure most sports witj a bit of danger involved, that isn't the more traditional team sports. I feel like this will gather people who wouldn't maybe just watch a bunch of videos of just one sport, and once people see all the categories they can go to those specific communities to see just that sport.
