Seems like every week's a big week for Facebook! This week saw the beginning of functionality changes for users which will "over time enable user 'profiles' to serve more as individual Web pages that could convey messages far beyond the current 5,000-'friend' limit," the San Jose Mercury News reports. The Mercury News said changes will include: users being able to categorize their "friends" into "separate and sometimes overlapping subgroups, such as 'family,' 'close friends' and ''co-workers'," and users able to "more easily post links, photos or videos with their comments into the 'stream' of information to and from the Facebook site [parents, ask your kids to keep you posted on how this works and whether they're paying attention to privacy settings in the midst of this]." Meanwhile, Information Week reports that "a New York teenager has sued the social networking site and some of its users because of a Facebook chat group where she says she was ridiculed and disgraced" . In such cases so far, the Communications Decency Act has protected social network sites and other Internet service providers from being held liable for content users post on their sites.
