While I do agree with the problems identified, I can't help but think they also made forums a lot better. Due to the lower discoverability and higher effort to actually join communities felt more personal. You interacted with smaller groups and came to know specific people. I still have friends from back then.
On larger platforms, I never had that. Even lemmy, which is small in comparison has enough people that I barely even think about specific users. Let alone speak with them on a personal level.
