I have always had a problem of not finding great resources for learning a subject from search. Almost all the time first page is full of SEO and Fluff content. So, I have spend an hour to find great content.
For instance, I have to open dozen of tabs then spent an hour to find great content from that dozen and voila, I have spent 1 hour and out of 20 videos/articles I could only 2 that met my needs.
So for me the broken part of search engines is the finding content when you're trying to learn new subject.
What's for you?
