Facebook fatigue is growing as users spend less time on the site. Younger users aged 18-29 report spending less time and anticipate decreased use. Fewer teens are using Facebook, possibly because their parents and grandparents are using it more. A study found that 61% of Facebook users have taken breaks from the site ranging from weeks to months due to reasons like being too busy, lack of interest, no compelling updates, too much gossip, and concerns about overuse. However, Facebook still has over 1 billion users worldwide and is focusing on growing mobile users and revenue from mobile ads to ensure future growth.
