I remember the bad parts, and they were less bad. Flame-war practitioners, racists, New Atheist axe-grinders, and mentally ill cranks were not exactly engaging in productive discussion, but they were still recognizable as authentic human beings with a life outside that particular obsession. Usenet and web forums allowed users to customize their self-presentation with avatars and sigs, and people often used the same nick across communities so you could see their range of interests in music or coding or whatever.

Compare that to e.g. Reddit today where successive redesigns reduced features that made each subreddit feel like a close-knit community of regulars, instead trying to get people addicted to endless-scroll engagement where everyone is a stranger. Or Twitter where, if you browse through the Nitter interface on a desktop browser, you can readily see that many strident political profiles are bots with a profile photo from “This Person Does not Exist” or African/Indian Subcontinent troll-farm employees.
