We dig Digg as much as the next web addict, but our favorite thing to do on the link-luscious site is sneak through the doors of DiggLabs. As the site acknowledges, stuff now comes in to the user-empowered community so fast that stories often whip down the page and back into the unknown before most people catch them. The Labs attempts to address this issue by devising "a broader (and deeper) view" of all this frantic activity. And it does it in the most graphically arresting ways: Arc, the newest app, presents stories in ever-widening circles of popularity; Big Spy pops links down the page, enlarging titles as they gain votes; Swarm treats links like tadpoles under a microscope—each small circle wiggles and nudges about. Our vote for best visual feasting, though, goes to Stack, which plays like a news version of Tetris. "Diggers fall from above and stack up on popular stories." Watch out for the vertigo.
