Besides you and your friends, that is.
I just noticed that the ads along the side of my page (if I click the "How others see it") are all about music: Study Blues Guitar, EZ Play Acoustic Guitars, Quit Sucking at Guitar (my personal favorite), Blues Ringtones (If you had a blues ringtone that would pretty much cancel out any blues cred you might possess, wouldn't it?), and Guitar Lesson Scams (I have to check that out).
So what's on your page?
