I think of it like this: no matter what happens in the mainstream, it shouldn't affect you. Just because some kid has a big-name sponsor, or they dress him up like the hottest stars of today does NOT mean skateboarding is "dead", or it's "dying" or it's uncool. That's all on you. And like HorseHead said, it goes in waves. Skateboarding is big, then it's not, then it's big, then it's not. As long as you are having fun doing what you're doing, that's all that matters really.
