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).
