the reason skiing and blading are both comparable but skiing is kickin it hard while rollerblading is dead is because skiing has been around WAY before any other action sport... except for surfing. rollerblading came around after skateboarding when a bunch of kids decided they wanted to do something easier because doing rails and plain getting around was too hard. so when blading was put up against skateboarding, everyone realized how big of a joke blading was because we already had skiing and skateboarding just made it look like a joke. blading is fun to do but if you want you progress a real sport, pick up skating... or mountain biking... or bmx. there's plenty of other better sports to spend your time doing.
