Not that anyone cares about my opinion...
I've noticed in recent years in the United States an addiction to entertainment - television, computer games, facebook/social networks - all which supplant interaction with the first person. Because of the huge amount of choices in distraction from our lives, I think that in the US people have stepped away from intimacy, not the sexual kind, but the emotional commitment to neighbors, freinds, and family members. Kinda also reflected in the amount of texting and sms we do, rather than call and talk with someone.
Having been been in both Korea and Afghanistan for extended periods, and socializing with various cultures (Serbs, Croats, Kosovar Albanians, various European, Russian, etc) I observed that the cultures that have little materialism and the connection to created entertainment like movies on demand or internet games have fuller lives, and place more value on relationships. Their addictions were social activities and family. So 'addictions' are probably cultural.
The next addiction in the United States, maybe the western world, will be entertainment related, probably three dimensional immersive games, movies, and television (3D entertainment in the home). I'm in agreement with Buxton, Gaham, and Llandy targeting a particular item; I'm just of the opinion it's more of a general addiction to avoid actually interacting with other people on a personal level.
Kind of like posting at Taleworlds. maw
