http://www.arduino.cc/en/Hacking/BootloaderThere are still a lot of people asking about burning the bootloader, and a lot still answers with "you need to buy an external programmer"

There's already a link to his site in the playground: Arduino Playground - AvrdudeFTDIBitbang
If he likes to add in depth explanations, I suggest to bundle it there and not split it to several different locations.
Or at least add crosslinks to each article.
