I would have to agree that I have been spending more time than I'd like to admit on facebook myself. I get up in the morning everyday and read the newsfeed like it's the newspaper while I use the toilet for the morning... lol
There have been days when I have been on there for about 2 hours. That's typically when I get caught up looking at other people's pictures. I get upset with myself when I spend that much time on there though.
Yes..its one type of addiction and it has been now our basic needs.I also spend more than 4 hours a day on face book which keeps me alert and gives lots of happiness to me.You may have some problems in your system or you have some restrictions in your IP address.
