Now, Google is heavily polluted with SEO garbage, junior-level blog posts churned out by what must be student assignments to "write a blog post about this week's programming assignment", and the truly horrible data scraping sites like xspdf or whatever. General web search is increasingly poor.
And Stackoverflow was great for a long time. Now it is mostly outdated (which usually means incorrect) Q/A data. Worse, the old information that should be retired actually blocks new questions with current answers because of the aggressive system of trying to prevent "duplicate" questions. It's not a duplicate question if there's an 8+ year (or even 3+ year!) gap between the date of the original and the date of the new one. Quite often, even if the original question is close enough to current needs, the answers are very unlikely to be correct now.
Prior to this everything was based out of tech manuals, now I can find good information fast, and memorize pointless trivia far less.
