The infamous blog pool known as Digg has seen a few overhauls lately, and has introduced several Web 2.0 elements into their design. On top of introducing various user-driven Top 10 lists, they are now including (testing only) a Podcasting page, which includes user rating in a similar fashion to how Digg stories are rated. The more successful the site, the more user driven and dynamic they are needing to be. With sites driven completely by user whims becoming more common, it won't surprise me when browsers and instant messengers start becoming more integrated into sites. The updates aren't particularly noticeable, but the podcasting is pretty neat.
