Facebook has another redesign in the works.

The wildly popular social networking site sent out invites for the media to come see a "new look for the News Feed" Thursday at its headquarters in Menlo Park, Calif.

It didn't give any other details about what those changes may include for the landing page where Facebook users can see updates from their friends and other accounts, The Washington Post reported. But that didn't stop many from speculating. 

TechCrunch pointed out that the site could be planning a more photo-oriented re-design of its news feed.

Tech Crunch's Josh Constine got to take a sneak peek at a Facebook employee's phone, which displayed the layout being tested at the time. It looked a lot like Microsoft Metro's interface, which featured text laid over large featured pictures, seemingly inspired by magazine covers. 

ReadWrite noted that Facebook was apparently testing a new layout in New Zealand, which changes where users' basic information, friends list and other static information is listed on the site.

Last month, Facebook redesigned one of its features last month - the search function, introducing larger icons and additional ways of viewing data on the page, The Washington Post reported. One of Facebook's most notable changes came in 2011, when the profile pages were replaced with timelines, kind of like a scrapbook of users' lives.

The news feed was first designed in 2006, but faced a makeover in 2011, which featured bigger photos and "important stories," determined by a company algorithm of what posts users were most likely to read. Later, the newsfeed reverted again to display the most recent stories on the top, The Washington Post reported.

Facebook users are almost always aggravated when the site launches a redesign -- but that frustration usually dies down within a few weeks, according to The Washington Post. It will be interesting to see how people react this time.
