Current limiting on outputs?

The "Light an LED" experiment shows an LED connected directly between POWER and leg 0, without any current limiting resistor. Is there a resistor on the GPIO pin, externally or internally? Or is this experiment just living dangerously?

Yes the are series resistors on the legs.
