Online classrooms aren't new -- and neither are social networks. In fact, Microsoft Research's latest project may seem a little like Facebook with a twist. The research lab at the Redmond, Wash. company launched a site that allows students to network with peers, share information, and build their own pages collecting information from inside and outside the classroom. Researchers collaborated with students to design it. The online destination is designed to help students learn more. The site was born after researchers at FUSE Labs examined Facebook and Twitter data and how it is used in Bing. They tracked URLs that people shared to see how news and information were gathered and spread.
