The Guardian has released an interface experiment called 'zeitgeist'. It creates an overview of articles and news that are growing and declining in popularity. The design team has posted a blog article on how it was developed.
There are three aspects to this work that i really enjoy
1. they are releasing 'experimental' interactions, which aligns the Guardian brand with forward thinking and new technology - very important for newspapers
2. the design team are exploring crowd sourcing and user behaviour to determine how they serve news - letting the users decide and influence
3. they are openly exposing their process and documenting the design stages - transparency in brand communications
excellent work. very jealous of this.
