Too Long; Didn't Read
There is no successful shooting without a target. Your rifle can shoot very loudly, but you will just scare everyone. If you have no target — you are just a maker of noise. If you have a target — you may hope to get a result and score bull’s eye. But when you have never made a user research, when you have no idea who exactly is your customer, what is your audience — you are just loosing your time, trying to sell a product to people, who don’t care about it. It is called “push technology” — we are selling our product because we want your money. Nowadays doing business this way — is just a show of incompetence. And of course, it will not work. At all. Never-ever. Really, you can forget about your profit, if you are doing nothing for your user`s profit.
