It's top HN because HN commonly sees complaints about quotes in Google Search not performing correctly; i'd link to some of these complaints, but the algolia search is needlessly fuzzy and doesn't seem to include all comments on HN.
I think developers and technologists use this feature often to locate people experiencing the same technical issues. Don't know what an error means? Google it. With quotes.
Something like that is about as key to using the web as anything. I've used quotes on searches to get an exact phrase since, what, 1995? The fact that has been broken for a long time and now fixed is absolutely worth top story of the day to me.
Am I missing something?
How did this become the #1 story on HN?
