Facebook is on a mission to take the social out of social media. They've announced changes to their algorithm that you're already seeing.
They're prioritizing ads and video from complete strangers over the updates from friends and family members. Those updates are going to be buried somewhere and you're really going to have to look for them.
As a user, this is incredibly frustrating. And as a business owner, it's confusing as I tried to figure out how to navigate this post algorithm change world where there's really no social and it's all just media.
