Interesting post from Mark Cuban titled "why you should NEVER listen to your customer" references an long standing Alan Kay quote "the best way to predict the future is to invent it"
Cuban then goes on to make the statement that having a vision and "self ass kicking" is more important than customer feedback. Take a read - you may think differently.
My question to you: How important is customer feedback an at what stage in company development? There's some pretty strong opinions on this one (fail early, predict the future, MVP )
What says you?
