I have been on reddit for just about 12 years now. Something I've noticed over time is just how hateful the place has become. A complete outrage machine. Every single sub became filled with it. I've filtered so many subreddits over the last few years, it's insane. I don't know enough about this place to be sure, but I do hope it doesn't become the same type of echo chamber of anger.
If i had to guess then maybe a bunch of instances could solve that with ads and selling big data (info of the users). Not that we would whant that but its the most sthealty way to do that.
