Ok, let's discuss the ideas presented in the article. The two forms main forms of regulation suggested near the end of the piece seem to be letting users control the amount of content/notifications that they consume, and flagging users who seem like they are exhibiting signs of addiction.
Most sites do offer options to control the number of notifications, etc, but most people just stick with the defaults anyway. Even if there were an option for "Disable infinite scroll for me because I can't control my procrastination", how many people do you really think would use it?
Likewise, if Zynga et al did implement some kind of flag for users who play too much, do you think it would make a difference? If someone is willing to invest 5 hours clicking a Farmville button, then a popup that says "We noticed that you spent the whole day clicking a button, don't you have something better to do?" probably isn't going to be epiphanic for them. Casinos and some gambling websites are required to do this now, and it hasn't cured gambling addiction yet. Just like adding a perfunctory "Please drink responsibly" to the end of beer commercials has had a small effect.
What could work? In some parts of Asia, security officers will forcibly remove people from cybercafes if they're showing signs of addiction. But most people in the west use home internet, which would make physical enforcement cost prohibitive. Laws could be passed that outright ban certain types of games. But a politician would look pretty silly taking a stand against Mafia Wars on the floor of a legislative body, especially given recent world events.
There might be a great solution, maybe offered in your book recommendation (thanks for that, btw). But it's hard to see what can practically be done about this problem, other than people exerting more self control in a changing world.
