Great advice. Launch early does not mean throw crap at a wall at hope it sticks. You do still need to make something that represents at least some of the function of your initial vision. Really you should make simple version and have a soft launch (not a ton of press) and when you actually "launch" it won't matter that you were out there with a half finished product because no one knew about you anyway. don't code locked in your basement make a demo and then get out there and show it to people and get feedback.
