Wieden + Kennedy, the guys behind the slogan ‘Just Do It’ redesigned the website (launched april 2nd). And they used 37signals collaboration software, that’s how I found out about it.
I like the new Wieden + Kennedy flash based website. The interface focus on information sorting by time in combination with tags. Different colors highlight people, companies, etc.. By clicking a keyword you enter a never ending 3d network with nodes. The focus is on discovering instead of retrieving.
I think good information design and storytelling will be the things that can really make a difference in the upcoming years. Websites are starting to look more similar due to effective user and usability research.
