For anyone who is interested, The Kindle Chronicles has an interview with Andy Weir about The Martian in the latest (episode 338) TKC. I am in the middle of listening to it now so no review/comments. But there are a couple minor spoilers in the couple minutes I have heard so far. Interview starts at 11:39.
