They were a long time coming, but Facebook finally underwent some major changes over the weekend that emphasize the social network's most popular features while borrowing a cue or two from Twitter.

The long-delayed redesign puts the focus squarely on a user's wall, where friends leave comments and share photos and links. The redesign combines the wall with the news feed feature, giving users a steady stream of updates about their friends' happenings, similar to micro-blogging sites like Twitter.

According to the company, users log onto Facebook to see just one photo, wall post or status update and the new design is supposed to centralize this information.

"We've made the changes rolling out today in order to highlight the most recent and relevant information that users value, give users even more control and ownership over their profiles and simplify the user experience," CEO Mark Zuckerberg said in a statement.

Advertisements are also affected by the new design, albeit only slightly. Ads have been moved to the right hand side of the page, which creates the possibility of running two ads at a time. Ads will also be served through the news feed, according to Facebook.

Facebook is rolling the new design out slowly, but for now, users can visit new.facebook.com to preview their profiles. Meanwhile, MySpace, Facebook's largest competitor, is also in the midst of a redesign.
