I often dislike it when I hear someone use that phrase. Granted it is a relevant question at times, but more often than not it’s used in the same condescending tone as “Did you RTFM?”
Sometimes…it’s good to have human to human discussions. Sometimes, the discussion participants will find serendipitous mutual benefits when contributing to the collective knowledge base.
That’s why I like Twitter. It doesn’t replace autonomous research, but it culls knowledge either not on the internet or not findable due to a gap between search terms and the desired content.
