A nicely done mashup app using Digg and Snap APIs. http://www.yourminis.com/swfs/diggexpose.swf
I haven't had the chance to play around with the Digg API yet and wasn't even aware that there's an open API for the SnapShots.  Anyone know where can I find the SnapShots API?

Digg today released their public API, and also announced a contest for "the most creative and innovative visualizations and applications developed using the API and Flash toolkit".

Here are some Flash apps created by Digg and its partner, Stamen Design at Digg Labs

Looks like eBay just released a new opensource API library for Flash. It is based on Actionscript 3 so you can test it out using your Flex 2 or the Flash 9 Pro Alpha IDE. Check it out here.
