My Facebook account is now part of the beta group for Facebook Graph Search, and I’ve spent some time taking it for a spin.
It’s clear this will be a powerful feature, but as Nate Elliott has already blogged, it feels like something Facebook should have built some time ago. What I predict to be the most common searches, such as “which of my friends live in London” or “people my friends are friends with who work at Ford Motors,” are powerful, but basic, features that users have been requesting for a long time. The first rollout will also be missing obvious road map features, including the ability to search for links and status updates that you or your graph have posted.
The success of any individual Graph Search reflects what data (and activities) users directly provide Facebook, and today, many of the online activities that Graph Search encompasses take place on other social properties. Facebook often facilitates the social graphs of the other social properties with Facebook Connect, but Graph Search cannot “see” into that data. The average Facebook “like” is also less meaningful than Facebook's development team hopes, as others have also blogged.
