Agreed. I think because emotions like rage or disgust are so quick, the consequences of those impulses are harder to mitigate when there's no cost to acting on them. Through eons of evolution, we've learned to fine-tune our fact-to-fact interactions to avoid most negative costs unless it is absolutely necessary. But online interaction has only been around for several decades, and we don't have those same hesitations. That's why I think Steemit and other crypto/blockchain-based social systems are interesting, because costs that we respond to (like money) are designed into the systems.
