Earlier quoted context omitted.
I've been noticing it for a while, the search quality gets worse and worse every year. For me, the red line was the Panda update in 2011. That update completely destroyed the search quality by bringing dubious quality news articles and ecommerce websites on the top of search, it never really recovered since then.
At this point, I basically have to append "reddit" to every search if I want to get quality answers.
The only time I'm using the search as intended is for programming error queries where it's way too niche for Google to append low quality news farms / ecommerce websites. That's the only type of query I still get good results.
