Hallway, a homework helper for high school students

Christina Farr:

Hallway, a startup created by high-school students for high-school students, is launching to the public today with seed funding from Fortify.vc.
The founders view their technology as the next logical step in education, and this summer, they’ve been testing the private beta at schools across the Greater Washington region.
Hallway is a website where students submit questions about subjects, such as algebra or political science, that their peers can answer. The site uses a Reddit-style system to rate the most useful questions and answers, which then rise to the top.
