Excellent at interacting with his fellow Tweeters, Kevin Rose has a Twitter feed full of @replies and shout-outs. The Digg founder knows what he likes and has no qualms about sharing details, whether his experiences with the new Firefox 4 or what he discovers perusing Techmeme.com. Recently he pointed out that Google Maps has the world's longest URLs and could probably benefit from a URL shortener. We gripe about that too, but the difference is, when Rose tweets something, people tend to listen to him.
