I've seen a LED been used this way in many tutorials. It's a very simple way of introducing people to Physical Computing avoiding complex explanations about diodes, currents voltages etc... but..
The digital pin 13 hasn't a resistor in serie.
There is a (LED with a resistor in serie) in parallel to the digital pin 13.
Using a LED connected between pin 13 and Ground is stressing the
ATmega328 output driver. The LED can withstand more than 40 milliamps and will survive.
Thanks for this video.
