It definitely was. I remember finding some amazingly insightful answers from people with proper experience. But that must have been nearly a decade ago now. Some of the most memorable ones were reflections from prisoners as IIRC some prisons had some sort of program where the prisoners could write answers and someone would post them on Quora. Interesting insights from murders, con artists and whoever else.

But it has been so long since that was the case. I've had it blocked from my search results for years now. Utter trash.
