Just finished adding integration with Google's API for web developers, thanks to some nifty code from Rael. Similar to the referrer list and RSS/XML syndicated "guest blog", I'm using a timed background script to update that data, since it doesn't change very fast.
I still can't get Rael's Amazon API code to work... as usual, it requires perl modules that I don't have, and can't get to install properly yet.
