The argument that apes have never asked a question “is a classic example of overstatement,” said Heidi Lyn, a professor at the University of South Alabama’s Comparative Cognition and Communication Lab at the Department of Psychology and Marine Science.

The network effect. It’s big enough that small forums get enough posts to stay active which keeps more people using it.
For example Lemmy has a 3d printer forum that has a few posts a week. Reddit has forums not just for 3d printing but for every specific model of printer and each gets a much activity as Lemmy’s generic forum.
If I’m searching for something, Google will show Reddit content but not Lemmy because there isn’t an answer on Lemmy.
