Facebook revealed the “third pillar” of their empire and it has been released over the course of the week, their new tool, the Facebook Graph Search. This is a social search engine, different from the standard fare and not a direct competitor to the likes of Google. It’s based on connections such as likes, check-ins, etc., where you can search for a subject such as “my friends who like Wow Internet” or “restaurants that my friends in Birmingham go to”, and there they’ll be. You’re able to peruse the reams of Facebook’s accumulated data in four areas: people, places, photos and interests.

One fairly large factor in this tool is that Zuckerberg and co has the services of Bing, which can answer queries and commands which the Graph Search can’t grasp. It’s currently in a preview/beta stage at the moment, and is slowly being rolled out to a small amount of users. You can apply to be one of those beta users here (US users only, unfortunately).
