I rarely submit questions for Google’s Matt Cutts, but I did submit one and he actually answered it in a video.
The question was, Matt – what are your regrets related to web spam. I specifically asked “Was there a key moment in your spam fighting career where you made a mistake that you regret, related to spam?”
