My dad frequents a very niche forum. A couple thousand users, many posts made daily, I'd guess a 80/20 split between long-timers/newcomers asking a question about that niche. Biggest reason they seem to be struggling? The person who set up the PHPBB forum 15+ years ago has long since moved on and there's very few left within that community who know what do if things don't work. One day it'll die/get hacked/server disappears and that'll be it for them.
