Awesome article. Shows some common failure scenarios of a real product, explains exactly what will happen and proposes an easily understandable solution. One of the best electronic lessons i've read for a long time. Finally makes you realize why most pcbs has all those weird components sitting around instead of just pushing the io-pins straight into the µC. While the avr might be able to handle some of the failures in certain scenarios it's still good to know how to protect yourself in case you use another controller or if you really want to be on the safe side.
