1. All of the Internet is Dopamine Driven
It's a "minor" problem for businesses when their employees lose more-than-normal (whatever that is) productive time, on the net. The best models for Net news sites are "frequent and compelling updates". So your favorite seven sites might chew half an hour to an hour of your time.
2. Quit being cavalier with Brain Words. Look at old literature and notice the huge chunks where people were bored out of their minds. First World Problem - Oh Look, people post notes on the Internet and sometimes too many at work!
Dopamine triggers with a "Payoff". So a good designed game will be ... "fun" ... to play.
3. Watch out for ReFraming. As an eight year old, I played Atari PacMan for so many hours our machine caught on fire. I think. So what. Me and my device Dad bought me. But gaming now has a lot of Sharing. Be careful. What exactly is the "gripe point" here?
