Debatable, I think. It's been literally years since I found any useful information on Quora. It's mostly spam now, even worse than Answers.com was back in the day, with the added bonus of a sign-in wall.
Note: if any person will find only one useful answer there, what the parent said will be true.
Of course this is pedantic and while I don't like Quota at all, I don't think it is up to us to judge what people may find useful (this depends very much on things like circumstances, age, mental capacity etc). What you might find trivial or even silly, might be an eye opener to someone else.
Quota is certainly not the best environment to get good qualified answers, but that doesn't mean you won't find one once in a while.
