People add reddit to searches because it gives high quality answers. That’s not a Google problem. That’s a problem with the Internet. Your average independent website or blog puts up some heavily biased answer that is just limited to that one writer’s perspective.
Google problem is that appending reddit is the only reliable way to get something different from shitty copywrited SEO trash sites. I don't know when I last saw real independent websites and blogs in the search results, probably ten years ago?..
Honestly the barrier to entry for a blog is very low and the benefit isn’t very high unless you spam it with ads, so who is exactly taking the time to make a blog?
