If are trying to get somewhere with the Digg API, I highly recommend this tutorial on accessing the Digg API with PHP. Remember to save the php files as a CodeIgniter library so that you can call it like this:

$this->load->library('diggclass');

I don’t post many Flex apps, but this Digg UFO app seemed simple, easy to use, and easy on the eyes.

Dominiek.com shows how the author built a .com website in 24 concentrated hours spread out over 4 days (hint: he used rails). Looks like there were problems when his link hit digg, so he posted the lessons learned. Thought it was a cool story for fellow developers.
