Deadlines make people do dumb things. Every time I offer a free digital document or an educational event that has a deadline, I can guarantee I will hear from several (or dozens of) people with ornate, well-considered and thoughtful arguments as to why they missed the deadline. Never mind that they had two weeks… the last fifteen minutes are all they are concerned with. If it's important enough to spend an hour complaining about, it's certainly important enough to spend four minutes to just do it in the first place.
