This could be the biggest thing to happen to the Facebook news feed since it was introduced.
It appears that the social network is quietly testing a massive revamp that will add a lot more news to the feed.

Facebook is experimenting with a new layout on mobile that highlights multiple news sections, with topics such as World & U.S., Sports and Food. However, the primary (and presumably default) section is still the classic news feed we’re accustomed to seeing.

Facebook confirmed to Mashable that it’s testing the new, sectioned news feed, in addition to the current format, though it’s unclear if the feature will ever get an official launch.

While the feature being tested isn’t entirely new — we’ve seen some versions of topic-focused feeds in the past on iOS — the format revealed in the latest Android-based screenshots haven’t quite been seen before.

In theory, this news reader-style approach takes users to all of the news they care about, housed in one massive hub. It would also certainly encourage users to get more news from Facebook rather than other sources like Twitter or Google News.

There’s also a tool to edit which feeds you’d like to see — meaning if you weren’t into Sports, you can remove it from the categories and include things like Music or Animals & Pets instead. Out of the gate, however, all topics are turned on by default, Critchlow said.

Critchlow, who saw the feature on his Moto X, says the article news feed also includes a prompt to add people he doesn’t know as Facebook friends.

“This feels like a huge departure from the traditional Facebook model,” he said. “There’s no ‘two friends in common’ label or anything like that. Perhaps there’s some intelligence behind the scenes but nothing immediately obvious.”
