That depends. Are you able to talk with that person about his experience?
There was a spelling error that was later called out. It bugged me to see the error, and I thought for sure it would get addressed during the show as part of a joke. But then the punchline didn't happen, and the slide kept on going. But then one of the Twitter Q&A questions pointed it out. I was wondering if this was a legitimate error or if it's intentional (because *someone* on Twitter will surely point it out).
