Just isn't suited for Western palettes. You have to look at the way respective bigger social media platforms took on in the East versus in the West. Imageboards in the West are dead as all hell too in reality. 4chan is immortalized in internet anthropology, notoriety, mass media, and in language. 8chan took off because it was it's retarded little Reddit spin-off. Imageboards in the West were never big, never will be. 4chan is unique because it was created as a fun was for people from an already well established website to interface in a way that they thought was interesting. Textboards are only good for discussion. Sad, but Westerners just don't like discussing things. No, they like networking differently. You can just look it all up, it's in English after all. Archive culture, question forums, that shit is far bigger in the Global Language than it is in Japanese, thusly, you don't really need to talk about it as much. Not so hard to find something you want to discuss and have it already had been discussed and said discussion being documented for everybody else to take from. Imageboards are also dead in the West because you don't really have to be apart of them to enjoy their fruits. Archives, YouTube videos, Wikis, the list goes on. As for textboards, Discord and Reddit probably, I don't know. When you have these "DIY" megaforums you kill an incentive to make your own place. I think Infinity scripts might have done this for the IB Dev scene. When a retard can make their own forum or chat room for thousands to join in three clicks as opposed to a competent person せっかく developing their own, there isn't much of a point.
