Things that might depress me are violence, theft, disease... Basically, people suffering through no fault of their own.
That's not what we see on a place like Reddit. While the creatures that lurk within the depths of r/buttcoin or r/btc are no doubt miserable, it's an entirely self-inflicted form of misery. It's not a question of intelligence, or access to information, or anything other than outright stubbornness to update one's own worldview when the thing you declared dead 17 times just made a fresh ATH. That's comedy.
Maybe that's just my sense of humor? I like to make fun of people, and sometimes we take ourselves too seriously. SN for example is full of complete schizos, but I love them all the same. I'm probably one of them, after all.
