The proliferation of these sources have torpedoed my Google effectiveness.
Not only do these sources amplify themselves, they are of near necessity targeted at simple use cases. The result? Google has ample popular material filled with my relevant keywords but void of any usefulness to anyone not just getting started. As it happens, the people with the most questions _are_ just getting started, and do find the results relevant pushing content on the margins further down the list.
Worse still, with Google's increased focus on natural language processing, their seeming approach of "what you're really asking is..." makes loose queries even more difficult. Definitionally the most common questions aren't edge cases, at least not the single one you're interested in.
After all these years, I think I need to retrain myself on how to Google (distinct keywords no longer cut it unless I have a sequence where I can look for an exact match), and recently started falling back to other search engines with some success.
Edit: grammar (believe it or not)
