Will Facebook and Twitter Keep "Paranormal Activity" From Turning Into "Snakes on a Plane"?

Four years ago, the movie, “Snakes on a Plane,” became a genuine Internet phenom well before the movie was in theaters. Which, in the end, only showed that online buzz had negligible impact on the viewing public, given that the movie’s box office turned out to be tepid at best. But will another small film, about a demon-plagued couple with an infrared-equipped videocamera, called “Paranormal Activity,” prove that the chatter of Facebook and Twitter has more legs today?
