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.
the bitcointalk forum is still active today, as there are so many people who want to learn in this forum because the bitcointalk forum is where we learn and expose our opinions about what has happened to this forum. so we should make good use of bitcointalk forums.
