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.
It's the removal of a down vote count. It's the same problem across all social media. People spew absolute outrageous comments... Get 3 likes or votes, and they think it's a positive score.
The reality is 10k down votes and 3 likes from bots.
It's really changed the internet landscape and ultimately society. We hide dissent.
