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.
The politics are left of center on social issues, but I wouldn’t say it’s as bad as Reddit. I see a lot of anti-trump stuff, but that has nothing to do with his politics.
