There is not one community. Something anticipated as far back as 2010: Seb Paquet’s answer to Does Quora actually need a community? There are clear splits in the community, enabled by the fact that different Quora users see very different feeds, determined by the topics and people they follow.
quora numbers by the departed Laura Hale demonstrated this with what statistics she could glean, and it is corroborated in all your experience. American Quora users notoriously know very little of what happens in the Indian Quora, and their demographics and interests are vastly different. Most Quora users have no idea who the Discord teens are, or who the Insurgents are. I certainly know very little of the Venture Capital old core of Quora.
