So the average user spends 1,400 minutes on facebook each month - about 23 hours and 20 minutes, or about 45 minutes a day. This figure could be really skewed if it tracks log-in time, not actual eyeball time (although that seems unlikely to me, looking at the daily number), and a lot of usage is probably games, but it's still massive, and, to me, somewhat disturbing.

Still less time than TV (2.8 hours/day[1]), though.
