Talk to your users! Before we started building our product, we spoke to hundreds of people in our target audience. We asked them their needs, their problems, and most importantly - what they wanted. We could zero in our solution to their problem by uncovering what they wanted most. So go talk to everyone you can about your idea and see what the audience you want to serve thinks about it.
