It'll have to be tested, but I'm not sure Perspectives will do what the 'reddit' query does for many people. I can only speak for myself, but I typically would add 'reddit' to searches because I was looking for thorough information on a subject, and I was certain there would be some random subreddit out there full of experts and enthusiasts on that specific niche topic. I don't want social media or influencer content, I want content from people with extremely deep knowledge about very specific things.
