For me, the questions around the gambling industry - and the possibillity that cash gaming may become legal in the United States - is less about morals and more about how dull that news is. As a sector, gambling is so conservative in its products (i.e. the games) that there's just very little to get excited about, and a key example of how behaviorism alone leads to uncreative design.
That's the subject of my article this week on TechCrunch.
(By the way, I know I've been very quiet for the last few weeks. This is because I emigrated, with all the attendant stresses that that involves. Will be back writing regularly soon.)
