I just did the same thing - logged on to my facebook account after many years, and I’m not having the same experience at all. Old friends, neighbors, and relatives posting disappointing amounts of AI slop, some local news it suggests I follow (something about a hairdresser getting fined for refusing service), one particular former neighbor posting an endless barrage of AI-generated religious slop… and that’s about it. It wasn’t interesting a decade ago, and it only got less interesting since.
