Unfriend people who do not post to Facebook or engage with anyone else. You'll find your posts start getting reach they never did before. Why? Facebook only releases your posts to a few people at first and watches what they do with it.

Especially now, with 'Glee,' it's allowed a lot of kids to love music and performing at a young age. All ages watched 'American Idol,' but I think it was nice to be able to show kids, 'Hey, you can be here, too.'
