The Washington Post has a wonderful front page story today of a college student who was abandoned as a day-old baby and 20 years later used Facebook to find the two teenagers who had rescued her. It is both a heart-warming story for the holidays and an example of the power of social networks. Facebook is a fun for most people, but it is also growing into a tool that can be used by lawyers to find heirs, witnesses, and other "lost" individuals. Enjoy the story, but think about how you can incorporate Facebook into a law practice beyond just a marketing tool.
