Most of my Facebook and Instagram is full of other people sharing good things about their lives. I know the cynical internet commenters will insist it's all fake and that they're only putting on a show, but the reality is that most people in my circles are doing quite well and are generally happy.

I'm also part of several online communities and even forums where most people are doing well.

There's nothing about the internet that requires people to bias toward being negative and cynical. The cynicism does tend to collect in certain internet bubbles and especially certain cites that cater to outrage-as-entertainment (e.g. front page of Reddit)
