I’d say you are spot on. I started Facebook in 2008 and the first four years were fun. Then it started its downhill slide until a couple of years ago when I couldn’t stand to look at it anymore. I actually looked at it the other day and it seems to have gotten better. No rants, or “news”, or memes, or the other junk peopole started sharing endlessly. Maybe it was just a fluke. LOL!
