Google Buzz (http://www.google.com/buzz)

Parents need to know that Google’s free social networking site and messaging tool makes adding friends as easy as emailing them -- or just accepting the recommended contacts from the service itself. Google's attempt to compete with the increasingly popular Facebook offers many of the same features and network-expanding focus of Facebook. However, there is concern -- just as there is with Facebook -- over a lack of privacy controls, primarily because it automatically integrates its web-based email program, Gmail, with Buzz, meaning anyone with a gmail account becomes part of the social network. Parents, make sure your teen selects “private” settings and opts out of showing the list of people they’re following and those who are following them.
