At least you can get good at playing solitaire, but you can't really 'get good at Facebook'.

Unless you're literally mindlessly staring at known data, you're learning. Social status updates and such are essentially a game, and they teach various aspects of social politics.

Dubious what useful skills most people can actually get from that but you can definitely "get good at facebook", as you put it. (And before anybody jumps on me - I hate facebook and I despise the completely fake life that comes out of the gaming aspects of facebook, but I can appreciate its values as a game designer)

> Unless you're literally mindlessly staring at known data, you're learning.

You can learn doing that too. The subconscious is an amazing thing.

The only way to win that game is not playing at all

Tell that to "growth hackers" and "social media marketing managers."

You don't see many people walking down the street playing solitaire though.

Candy crush on the other hand...

Hacker News perhaps?
