I had joined Reddit twice in my lifetime but was not actively using it, and maybe that’s the reason I’m not very familiar with this forum culture.
I would say that Lemmy is by far the most responsive SNS in terms of the community engagement that I’ve ever used.
I feel like Lemmy is substantially less combative. Reddit has become so very hostile over the years and every thread felt like someone was about to start a fight. Not that there isn't any here, but there feels like a normal amount, rather than an over-representation of people spoiling for a fight.
Agree to disagree is the right value to embrace in this kind of situation I supposed.
