No one kills more time on Facebook than the mother of a 3 year old. A study found moms of kids younger than 5 are more active on Facebook than anyone else. Mothers of kids between 6 and 10 are on less. Then I’m guessing it might go back up a tick as you want to try and check-up on what they’re up to. But mom’s with kids under 5 are the most active Facebookers. Escaping to a world where some people may act like toddlers, but at least they don’t have to clean up after them.
