If your Facebook feed is worthless, it's your fault. Either you have nobody you care about or you like worthless stuff. I'm connected with family and friends, I'm following interesting people and liked interesting pages. My newsfeed is full of great content, from people I care about or page with content I want to read/watch.
Perhaps worthless is extreme. But its not nearly as interesting as insta/snap
As someone in my mid twenties, I spend far more time on instagram and snapchat than on facebook. If facebook was to disappear tomorrow, it'd probably be okay with me. Imagine for a second if Facebook hadn't acquired Instagram. Attention shifts very quickly in the digital world, quicker than a lot of people think.
