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.
You can switch to a new instance and still stay on lemmy. You can even join certain instances that defederate with other instances they (rightfully or otherwise) deem problematic.
Good luck in your search for your digital commune that best reflects your values. Maybe you’re already there and you don’t know it yet. Peace either way, welcome aboard.
