Did You Check Out Andy Weir's AMA on Reddit?

I'm super excited for Ridley Scott's upcoming movie, 'The Martian.' The film is based on a science fiction book written by Andy Weir. I am currently reading the novel, so I didn't actually go through the author's Ask Me Anything that was on Reddit today. I'm worried about accidentally reading any spoilers about the book. For those of you who already read the bestseller, you might enjoy his AMA. Check it out here.
