As for connecting to people, you drag and drop the connect button into a folder name which you want their posts to show in. For example, You can create custom folders for friends, family, coworkers etc. After that, you drag the connect button into that folder. And each folder creates a custom feed from only those people for you.
I am open to brainstorming more ideas.
2013-2014 the algorithm got more foused on non-friend posts aswell as making the prioritzation less about "likes" from friends and instead some opaque engagement metrics. Groups had to "promote" post to get their prior reach to subscribers.
Also videos started to be posted around that time?
