I run an active forum in the DIY space, and another site that aggregates new build threads from hundreds of niche forums. Forums for people building cars, motorcycles, boats, airplanes, cabins, musical instruments, etc.

The classic forum format and tight-knit communities are ideal for what are called "communities of practice": like-minded people who get together to help each other build/create/make/do something. A well-moderated build thread is best suited to a classic linear non-threaded posting format, and that's why thousands of niche DIY forums still exist.

Pining for the forum heyday is common on social media now, but for niche DIYers, that participation is still a daily ritual.
