I still use Reddit, Youtube and Twitter on a daily basis. I get to choose what to follow, how and for that, it's informative (and a time-passing activity for sure) and useful.
Facebook, on the other hand, is an all or nothing app in my opinion. It's difficult to distinguish between who to friend and who not. Close friends and family members, I keep in touch with through WhatsApp, text and whatnot.
As an entertainment (or informative) platform, Facebook is even worse. Sensationalism and misinformation is rampant, or you're bombarded with ads. And you're not really allowed to interact or disagree without getting into a de-railed discussion.
On top of that, you're comparing your life with those of others (' highlights). It's a useless and depressing timesink (which Instagram is as well for those exact same reasons).
I'm glad I quit Facebook (for 99%).
