Of course, other posts won't disappear completely. If you are relying on Facebook as your source for news — as Pew Research found last year that 30 percent of social network users do — or to see posts from businesses or other pages you've liked, those posts will still be on your feed.
And over time, those kinds of stories will get better placement on the feed if you like, comment or click on them. But don't be surprised if you're seeing more updates from friends in the next couple of weeks, while the News Feed adjusts itself.
These changes probably sound like a pretty good update to Facebook users who use the social network to, you know, keep in touch with friends.
But Facebook did caution that publishers could see their "post reach and referral traffic" take a hit as a result of change. That's a recurring problem for publishers as they try to crack the secret of finding readers on social networks while weathering algorithm changes.
Facebook also said in the post that users should also see fewer posts that tell you your friends liked or commented on someone else's post — a type of News Feed post that Facebook said "many people have told us they don't enjoy seeing."
The social network also "relaxed" a rule that prevented users from seeing multiple posts from the same source in a row, so that you should rarely run out of things to read on Facebook — in case you were worried that you weren't already spending enough time with it.
