Facebook's facelift

Second-largest social-networking service Facebook just unveiled its biggest overhaul in 18 months, Technology Review reports. “Besides adopting a new look, Facebook is introducing tools that will enable its users to learn more about their social networks and more easily conduct electronic conversations among multiple people simultaneously.” The article adds that the service tested its new look and features on more than 100,000 members. And, although it’s famous as a service for college students that got its start at Harvard, “less than half its users are currently in college,” Technology Review reports. The rest are in Facebook’s networks for businesses, geographic regions, and high school students.
