Facebook peaked nearly a decade ago. I opened my Facebook profile just for sake of it sometime ago and many of the profiles were just remnants of the past.
Of course, many of them have moved to Instagram which is even worse [the desktop site must have been made intentionally this bad] or just communicate via messaging apps [looks at Whatsapp].
Reddit was quite good until they killed most third party clients and now, overrun by bots as well. It had it's moderation problems [a lot] but still decent. New Reddit UI is a disaster.
There is Lemmy [a decentralized option like Reddit] and even Digg is in public beta now.
