Facebook certainly has many fans.

'The Social Network,' the silver-screen story about the creation of the popular site, debuted at No. 1 and earned an easy box office victory, with an estimated $23 million earned.

As expected, the movie's positive word of mouth, strong reviews (including much Oscar buzz), youth-appeal subject matter, and canny marketing (like that wonderfully viral trailer) ensured plenty of moviegoers would "Like" the Facebook drama. Among director David Fincher's movies, 'The Social Network' ranks as his third best debut, after 'Panic Room' ($30.0 million) and 'The Curious Case of Benjamin Button' ($26.9 million).
