Forums are not great for usability though.

You need a unique login for every forum, notifications are a mess and usually via email, the UIs are poor and difficult to use, every forum usually has a different theme with different locations for buttons and settings, there's no real time way to communicate so everything takes forever, and everyone has stupid profile footers in their posts that make you scroll twice as much as you should have to.

There are also bugs like quoting a post that has images reposts all of the images again and creates even more pointless scrolling. Or forums that lack even basic image resizing so someone uploads their 24MP photos and it goes way off the side of the screen and makes the post take ages to load.

I'm sure it could all be fixed somehow, but current stuff is just awful and I absolutely dislike interacting with forums.
