A new Associated Press/CNBC poll shows half of Americans think Facebook is just a passing fad. 46% say Facebook will not have any staying power, while 43% think it will be around for the long haul.
But here's the numbers that really should give Facebook executives pause - 57% say they never click on ads or look at sponsored content. Only 4% say they use the ads.
As Facebook gets ready for an IPO that could be worth as much as $100 billion, there's also a generational gap about whether the social networking site is a good bet according to the Associated Press.
Young adults, a majority of whom log on to Facebook daily, are more willing to dance to their hoodie-wearing piper, 28-year-old CEO Mark Zuckerberg. Among Zuckerberg's peers, adults under age 35, 59 percent say Facebook is a good bet. Compare that to the views of senior citizens: Only 39 percent age 65 and over say Facebook shares are a good investment. Nearly half of Gen X'ers (ages 35-44) say the company is a good bet, as do 55 percent of middle-aged people.
Those under 35 are the generation most interested in Facebook's IPO because they've grown up immersed in the social network. They were the first users, logging in from their college dorm rooms. Later, Facebook expanded to allow high school-age and even younger students to sign up. It's become an integral part of their lives, giving them a launching pad to spread the news of life's major developments through posts and pictures.
