Startup news sites are not a business plan and relying on them is a mistake. Similarly, tons of material about startups is just advertising, the majority of it should be ignored.

Building something people want is really hard, can take a lot of trying and failing, and is the reason why almost every startup fails. You have to keep trying until you figure it out. Think about who your ideal customer is and how/where you can find them. Then do that until you have many of them.
