Although Xanga and myspace have a lot of high school students as users, and facebook recently launched a separate site for high schools, Sconex is actually designed for high school students, with functionality that lets students enter their classes and show their schedule on their profile page. They can also enter teachers. And students from each active school actually serve as Sconex appointed high school advisors. They even say that it is something worthy of putting on a resume:

Reps get special privileges on the Sconex web site and are first in line for free Sconex gear. Plus, taking on the position and responsibility of managing your school's community is something that college admission officers love to see in an application.

Sconex, if I had children, would certainly be a site that I would allow them to use. That's a bit more than I could say about some other sites. Maybe even encourage them. And that's a lot more than I could say about some other sites.
