I don't know, I disagree, that hasn't been my experience.

Several years ago, the first result for web topics was almost always MDN. These days it's usually one of those SEO programming content farms for beginners.

The other thing that annoys me to no end is that Google's own language settings don't work. I live in Japan, but I don't want Japanese programming search results. I have told Google to only return English language results, but it ignores that most of the time. The only way to force it to use English is that sometimes it asks if you want English results only, but you can't force it to do that to begin with.
