College.com is hoping to fill the niche that Facebook used to occupy—as a networking site open only to students from colleges in the U.S. or Canada who have a .edu e-mail address. It features campus social event postings, class schedules, and user rankings of professors. Cristina Castillo, 21, who has been a member since College.com's launch, primarily uses the site to instant message with friends and to find out what's going on at her school, Florida State University. Unlike Facebook, Castillo says, College.com remains personal because it stays specific to what's going on around your campus, although you are able to "friend" members from other colleges.
