Ahhh, speaking of traditional forums, I personally like https://www.skyscrapercity.com/, it's still surprisingly active. It's also the only where I can get the most updated news about public transport/infrastructure in my country (Indonesia).

Also I just remembered that rateyourmusic apparently have their own forum too: https://rym.fm I've never taken a deep look at it, but it's surprisingly... active?
