If bulletin board software was made today and was free of the archetypes and styles of the 90's and 2000's would they be more popular today? Spent a lot of time on them during those years and I still find valuable information there whether it's how to fix a car or what strategy should I use to play a certain game.
I think these communities were more tight-knit. They had some modicum of moderation as you typically had to sign up and typically you had to be a good citizen for a while before posting threads. This is in comparison to many social media where you can begin trolling with little to no effort.
Reddit favors gamification or conforming to popular opinion. Many of the forums I frequented didn't have any sort of rep other than post count and maybe join date to see seniority.
I see a lot of sites I used to visit go this way including the forums for Magic: the Gathering. Based on user numbers and the rise of social media platforms they are very likely going to substitute for the old tight-knit forums of yesteryear.
