leading a more interesting life? if you game 6+ hours a day and porn is an admittedly "large part of your life" it seems like a hollow life. porn and video games are fun things, but they are not the foundation for a fulfilling life.
I agree with you on a personal basis - I try to be moderate about most things I do as well, juggling work, university, friends, games, creative output (drawing, photography), reading, movies, other activities so that I don't get caught in a fixed schedule of just one or two of these things (even though over some periods of my life, I failed at that :O). So for me, a life with 6+ hours a day gaming and porning around on a daily basis would be hollow too/not what I want out of life.
Then again, define fulfilling life. You know, maybe someone who plays videogames 6+ hours a day does this because it really is his one big passion - what should he do? Force himself to read a book or to join a sports team? As long as it's not an obsession born out of depression or something similiar and if he leads the life he wants (including a relationship or not), to each his own. Your post seems kinda arrogant to me in that regard.
Also, I don't agree with the article - obviously - but the general thesis that people become at least awkward when it comes to relationships is something I could get behind. General IMO face-to-face communication skills might have declined somewhat with younger people, then again maybe it's just a shift and it takes some years of time for society and rules of society to adjust to new situations like Facebook or the overpresence of sex and porn in all media. I don't think we're in danger here. I mean, the same kind of melodramatic "WE'RE DOOMED" was around every time a new media system got part of the lives of the majority (*insert Nintendo-joke here*).
