While 75 percent said they had “liked” a profit or non-profit organization on Facebook, 69 percent said that once they “liked” the organization they rarely or never returned to the fan page, according to a new survey from a group of professors. Only 15 percent of the respondents said they visited organizations’ fan pages weekly. “It’s clear that the 18-29-year-olds are not as invested in an organization as the organization may think they are when they click the ‘like’ button or click ‘follow,’” said Dr. Tina McCorkindale, an assistant professor in Appalachian State University’s Department of Communication and a rising social media expert.
