Facebook announces another round of News Feed tweaks, here is what's changed1
Even though Facebook has said numerous times in the past that it doesn't matter how long people spend on Facebook, but rather the quality of time spent. By that principle, Facebook announced a new rounds of tweaks to the News Feed feature.
After running a bunch of surveys last year to ask people what posts they thought were worth their time, Facebook has decided to update the News Feed accordingly. So, the updated News Feed should provide you with links that Facebook thinks you will find worthwhile.
Apparently, these changes will be introduced gradually, but you'll probably don't notice them Facebook says. There's no deadline for when these changes must be implemented, but they're likely to be rolled out over the coming weeks.
