Despite being but 9 years old, Facebook is now a ubiquitous part of our lives. For many people, it is hard to imagine how they would get news of their friends or their "friends". However, how Facebook can be used is still a confusing matter. What is socially acceptable on Facebook and what isn't is poorly defined, which can get serious when it coincides with legal matters. Recently, a US Court of Appeals clarified things a bit more by stating that "liking" on Facebook is equivalent to putting a sign on one's front lawn, which makes it free speech protected by the First Amendment.
