Yea, the whole "Scope your search to reddit" idea always comes up, but it just seems like a really terrible idea. How does one know for sure that the results from Reddit are any more accurate or authoritative than random SEO spam? There's very little curation or moderation there--anyone could post anything there. I could go there and comment on a subject that I have zero expertise in, make it sound confidently correct, and your reddit-scoped search might find it. Why would you trust it?
You can read whole conversations. Most of the smaller subreddits that this type of search picks up are actually filled with people passionate about whatever subject area it is. In general, I find it very trustworthy.
If you post something wrong on the Internet, someone will correct you.
I always get downvoted for this, but I much prefer Quora in my search results to Reddit for this reason. Although they've abandoned it now their earlier stringent sign-up process requiring that you are a real human means you're more likely to come across an answer with a real name and/or professional creds attached to it, and those answers imo tend to be higher quality. Of course there's all the copypasta spam (mostly) from India but that is easy to avoid since people use their real handles not anonymous sock puppets. Unfortunately they've decided to go down the route of promoting their AI chatbot in search results which for me has significantly degraded the results
