One of the applications in Facebook is called parking wars. You park your car on your friend’s street and they ticket you. AS you park, you earn more money with time. As you reach certain milestones, you get cars.
It is amazing what one can learn on this game. Eventually, you figure out that just ticketing everyone else will not give you anything in return. If you let some people park on your street without ticketing them, they will return the favor next time.
I play with the wife and I tell her to park in my street and I won’t ticket her. Just like in real life, we are a team. Pretty good deal.
