I get the point the OP is making. Which is don't build anything without being sure people need it and will use it. I can't find any reason to argue with that. Sure, there are examples of people building things that later went on to be huge. But 99% of the time, you just have to talk to people and find out what problems they want solved. And its not like I have known this for a long time. I used to think I knew what people wanted, without asking them.
