Yes! Long experience has taught me that I can either look dumb in front of a small, friendly audience of early testers or a big audience of people with inflated launch-day expectations.
Not looking dumb is not an option. It is a big fucking world, and it will never fit inside the 3 pounds of meat that people somehow expect me to think with. Especially when some of that meat is dedicated to things like the ego and false pride that tell me that my big launch will be magically perfect because I am so smart.
