The document summarizes Facebook's announcement about evolutions to its design and user experience. The key points are:
1. Facebook introduced a richer, more visual design that emphasizes images and photo albums. It also separated the news feed into dedicated sections for friends, brands, music, and articles.
2. The news feed sections include a friends-only feed, a feed for followed brands and celebrities, a music feed of friends' music and artist updates, and an articles feed of content from friends.
3. Facebook applied its mobile interface to desktop, moving navigation to the right and announcing new posts with a grey line. This focuses more space on content with only two sections for feed and advertising.
