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.
Strong emotions drive participation, which in a For-Profit Social Media site means more eyeballs for more time, hence more money from advertisers.
As it happens adversarial hate (i.e. two sides, pitches against each other, humans hating humans rather than just a hate for something generic like "poverty" or "light beer") is amongst the strongest and certainly one of the easiest to create.
My hope is that in the absence of a profit motivation and of popularity-score-keeping in the form of karma, the fediverse won't turn into that specific kind of swamp. That said, only time will tell.
So, are you saying that "reaching across the aisle" and hearing alternative views are bad things? I get avoiding hate speech and excessive negativity but is think a happy medium would be more healthy.
