Just Ship It
brainpad.orgThe caveat to this is if your software will be in an App Store, initial bad reviews can effectively kill the product.
That is the real only enemy and this case, and one that I myself fear. That is why you must back yourself up with a good blog with announcements and an goal descriptive product page (showing the user/client which way we're heading and what's the vision).
A good vision description (sales pitch) can sell almost anything.
Thanks for reading by the way!
