An anonymous reader writes: An article in the NY Times makes the case that Graph Search, Facebook's recently unveiled social search utility, will be a test for users of the social networking site which will have consequences for the internet at large. The test will show whether people are willing to take the next step in sharing parts of their lives, and whether social search is the future for online interaction. '...the company engineers who created the tool — former Google employees — say that the project will not reach its full potential if Facebook data is "sparse," as they call it. But the company is confident people will share more data, be it the movies they watch, the dentists they trust or the meals that make their mouths water.' CompSci professor Oren Etzioni says it's a watershed moment for the social internet because of the scale at which Facebook operates. A decade ago, people began making the choice to share their lives online; buying into social search would be the biggest step since then.
