I don't think that's the point. The point is that some things naturally prey on our tendency towards addiction. There are a lot of people who (like this guy) get REALLY uncomfortable when they aren't pinging their inbox constantly. And social sites are getting downright scientific about addictiveness. "How'd we do this week?" "Time on page is up by about half a second and return visits is up 0.3%". So much innovation has happened around shortening the distance between you and something amusing/engaging... To the point where you could just surf around Facebook and the web and really never get tired of it. For a lot of people there is an "angel" sitting on their shoulder saying, "What the hell are you doing with your life? On your deathbed, are you going to look back at this and be proud/happy with how you spent your days?"
