I still prefer forums.
My brain just doesn't really mesh well with the real time nature of chat and Discord. I know most people sit in there, idle, until there's a comment or remark that interests them. I find that really tough to do. If I'm there, I'm switched on and focused on every message and notification, even if they're not really of interest to me. I noticed with IRC, if I was in the chat that was it for my evening - I would not be doing anything else like browsing, watching videos or TV, or playing games. I'd be watching and waiting for every message that rolled in.
