Before investing a lot of time and effort developing products, you absolutely must find out what your market wants. Far too often, people develop a product without finding out if their market is really "hungry" for the information. Then they are surprised when their "Million Dollar Idea" doesn't make any money.
When you can find an unserved or underserved need that your market has you are on track.
If you don't know what your market wants, ask.
