Focus on stories with content versus shares and likes on the Facebook page
Injects code in the Facebook pages that analyses the type of stories you are shown. Based on their status, they are made smaller and more transparent based on how unimportant they are. The focus is on people writing their own content or going to events, versus shares and likes.
Note that all changes on the Facebook page are done via CSS. In case you want to change the way stories look you can use an extension like Stylish to tweak the rules.
