Facebook has again made some changes to the way they display content in your News Feed in hopes of bringing a better balance.
Finding a good balance between too much content and not enough content is a tough task and Facebook has been taking user feedback to heart on this. Facebook is once again changing the content that is displayed in your News Feed based on what they have been hearing. These changes all take place behind the scenes; there will be no app update required to get the new balance.
The first big change is improving the quality of content for those who don't have a lot of content to see. Not everyone has hundreds of friends on Facebook, and previously they prevented multiple stories from the same source from appearing. They are now relaxing this rule to deliver more content to those who would be interested.
Next up Facebook is trying to ensure the content posted by friends you care about remain higher in the News Feed. If you read the news from that person, or interact with them, Facebook will recognize this. The last change is that Facebook will make updates of friends liking or commenting on a post appear lower in the News Feed, if even at all.
All of these News Feed changes have been made by Facebook, so you may notice a change in the content of your feed.
