Digging is now easier after Digg has launched their new product called Arc. After BigSPY, Stack and Swarm, it's Arc from Digg labs.
Unlike the previous ones, the new tool is not browser-based and works on Adobe Flash Player. It gives you some con-centric circles that represents the stories hot in Digg. To quote the site:
Digg Arc displays stories, topics, and containers wrapped around a sphere. Arcs trail users as they digg stories across topics. Stories with more diggs make thicker arcs.
Just click on the circle that you want to read. The default browser will take care of the page! ;) Very simple and tiny (only 1.48mb). Go give it a shot! :)
