Way back in the day when Facebook was only accessible to students in college you had to actually go visit your friends’ pages to see what was going on. Then the Newsfeed was invented. After some serious skepticism, most of us got used to the feed and enjoyed having everything neatly organized into a single list.
But as Facebook grew larger, they realized they couldn’t show you everything. So they created the Newsfeed algorithm. Now, you only see what they want you to see. It’s basically like the mafia, explains College Humor.
