Did you even read what I said? I wasn't saying that WordPress is worse than NodeBB or anything like that. I said that it's nonsensical to expect to be able to move from forum software with categories, topics, posts, replies, chats, etc to a blog system which doesn't even have built-in comments AFAIK.
I like NodeBB's source, though it would be nice to have real documentation for it 😉 Maybe even something like consistent JSDoc comments?
Thank you for the kind words, by the way. I'll keep updating this post from time to time 😊
