Facebook’s Graph Search, the tool that enables plan-language search across information shared by friends or anyone on the social network is now available to anybody who uses U.S. English as their default language. It’s a useful tool, and as more people use it it will only increase in its applications, as new meaningful searches turn up new information across different parts of the network. However, privacy will become a much larger concern, as now nearly everything on Facebook can be looked up with a simple click of a button.
