If you want HS stuff and your highschool is into it, I'd actually reccomend Sconex. Some schools have no one, and some schools have 110% (spam accs, but there are still a lot of real students). Sconex.com's layout can get rather annoying at times, but if your school has a lot of people, it's better then myspace, xanga, or a HS facebook.

And it's superspecialized for HS's only, and if you HS is popular there, it has a lot of useful resources, like grouping by class so you can PM your class to ask the HW, etc.

Just my two cents.
