+1. I used to take the same position as ffhhj on this and I learned the hard way to talk to customers first before doing anything. I'm not saying that building in stealth mode without talking to customers can't work, I just believe it greatly reduces your chances of success.
Incidentally, I think the equally common advice of "solve a problem that you have yourself" is coming from the same place: you can't solve a problem without understanding your users.

So does this mean that it's okay to start developing a product if you yourself have such an (acute) problem even if you don't check for/with external customers first?
