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.
Those of us who were on the net in the 90s, we had to make accounts for every forum / community site we wanted to use, it wasn’t a big deal. Nowadays if you go over to reddit, they’re convinced any site you have to create an account for is doomed to fail. Even one like this one, which similar to email, connects you with a wider network outside of the one you signed up on.
