What is the nature of the forum? Is the quality post the most important? In my opinion, if a forum is full of quality posts, then it becomes a scientific journal. The forum I like is an easy discussion environment.
I think the forum is a place to learn and exchange information in order to learn from each other, I think bitcointalk still exist and now many quality posts so this can be used as a scientific journal about cryptocurrency technology.
I think so. The forum is a place to learn and exchange experiences. I have very little experience in the crypto market so I usually go to forums to learn more experienced people.
