A study by the Pew Internet and American Life Project also shows that the majority of Facebook users have gone on breaks from the site, owing those gaps in activity to the "tedium and irrelevancy of its content," NYT reports. "Among the crucial younger demographic — users ages 18 to 29 — that first propelled Facebook into prominence, 38 percent said they expected to spend less time using the site this year." And though Facebook is still the most popular social network out there, Wortham posits that it's possibly no longer as key to social survival as it once was. "As it has become nearly universal, Facebook may have lost some of its edge — or, at the very least, it may no longer feel novel or original to some of its users," Wortham writes. "Those cracks in Facebook's veneer have provided a market opening for other messaging services among young people in the United States and worldwide."
