Krishna Dagli writes to mention a BusinessWeek article about a move by Facebook to open up to the public. Up until now, in order to join Facebook you had to be an alumnus from certain High Schools, Colleges, or companies. Soon, individuals living in any one of 500 'geographic regions' can sign up. From the article: "People who joined Facebook because it was primarily a school-focused network may feel that it's losing a key distinction. As with the 'news feed' announcement, reception to this overhaul will come down to how well Facebook communicates. For the average student at New York University, for instance, little changes. The only people who can browse his profile before were other NYU students and that will stay the same. The change simply allows for 500 new groups to form that all operate independently on the Facebook platform. No one can browse all 9 million registered users."Update: 09/12 16:29 GMT by Z : Fixed latin conjugation. Mrs. Tomlinson would be so proud.
