Very interesting technology and potentially very useful if you’re looking at vastly larger scales of data!

Swarm is a new social browsing service that feels like a cross between StumbleUpon and the Attention Trust recorder. You install a Firefox extension to record your browsing activity, and the aggregated data is displayed in a Flash animation. From the site:

Swarm shows you what websites people are visiting, right now. Swarm is a graphical map of hundreds of websites, all connecting to each other. It updates itself every second with where people are going and coming from. As sites become more popular, they move towards the center of the swarm and grow larger. Conversely, sites that lose traffic move away from the center and grow smaller.
