Are you one of these people who is pretty much never away from the internet? Are you rarely on it at all, for whatever reason? Or somewhere in between.
I'm obviously in group 1, because I have to tend to not only two websites, but also a day job that involves... making websites. So I maybe get about 8 hours offline a day, and that's for sleeping.
I'm only offline when I have to be. Mainly during work or when I'm at my friends' house. If neither, then I'm all from when I wake up to when I go to bed. Even if I'm not active, I'm still on. GR and YouTube are up on my computer 24/7.
Most of my work involves me being on my PC, and since I often have to look stuff up, and respond to messages nearly all day, I'd say I'm only offline about 2 hours a day, plus the 8 hours of sleep I get.
