I wouldn't use reddit to find credible info about world events or trending topics.
However, it's an excellent source for finding information about hobbies and niche topics. The culinary subreddits have great recipe advice and I'll often go there to find best practices for food safety or unfamiliar techniques. Appending "reddit" to the end of my search means I don't have to sift through hundreds of SEO'd blog posts with questionable advice! For the time being, people don't SEO their reddit comments.
Now that I think of it, I actually do this quite often--Google really isn't what it used to be.
