I was searching around for some SVG radial background gradient something or other that I wasn't sure even existed a few days ago and the top hit to come up was a SO question that had been asked 7 hours before. Answered my question, too. I was impressed.
What's funny is when someone asks a question and you think "Oh, I'll bet I could answer this with a little googling." And the top result turns out to be the question you're trying to answer.
What's frustrating is trying to Google a question, finding forum threads telling the original questioner to use Google, and refusing to answer the question.
I was trying to look up an error[1] regarding Padrino the other day and someone had asked about the same problem I was having. The exact question I typed in had been asked on SO 6 hours before I encountered it and then deleted from SO, but Google had cached it.
I was sad the top result led to a deleted question without an answer, but was impressed an exact match to my question was cached 2 minutes after it was asked and was the top result (hopefully it will be dropped from results soon since it leads to SO's 404 page now).
