The Facebook Facelift is a self initiated project to challenge the form and functionality of Facebook. It's streamlined, structured, linear interface is more comprehendible, enhancing the user experience and absorbability of content.
The home page features many new benefits: the publisher toolbar enables users to post content from any page within Facebook, saving time in navigating needlessly through profiles; the streams' two-tiered filter (content type & content contributers) also creates a more coherent structure with the core elements retaining their position throughout most of the site; and the live feed displays a constant stream of all content posted in a users network, which expands upon mouse over.
Profiles also integrate with the system more seamlessly. Just as friend lists filter the stream by a select number of people, user profiles simply filter content to a single person, creating a clearer and more comprehendible layout.
