I feel exactly the same happened to those of us who started on FB when the craze hit -- we talked about whatever and it felt so low-key and exciting and was fun to find friends....
Aw - now I hate to say it: but FB is 90% fake...
In my opinion - filters are one big reason why so much crashed and burned; this picture-perfect nonsense is just killing our young girls, and it's incredibly demoralizing.
I would use FB - but people don't post sincerely and don't engage...so I got tired of trying. Plus the people on the MLM now pushing all their products make me run away even faster!
