The recent launch by Facebook of a new Graph Search service has generated a lot of Internet buzz.
John Battelle has an excellent piece up on what he thinks about it.
I have no problem with his points, but Graph Search will never be anything other than a niche service used by a small fraction of Facebook users.
The reason is that it requires multiple "operators" in the search string, and the average user has no clue about how to do this.
Consider an example Graph Search: friends of friends that are under 30 and single.
There are three "operators" that tell the search what to do: 1. Friends of friends, 2. Under 30, and 3. Single.
The reason that Google became such a search powerhouse is that not only did they put up a simple interface and box, but the system worked for the average uninformed user because they could just put in a single word, a phrase of two words or over time, they could input in a question using their same language format that they would use to ask someone a question.
Facebook Graph Search, in its current variation requiring a variety of operator strings, will work very well for search professionals, but will have little application by the average user, who has no knowledge of the use of these parameters.
