It is very hard to honestly evaluate your own idea, because it's, well, your idea.
You get to tell about it to someone. And when you tell and ask for feedback and help - voila, you are not a pure solo founder anymore.
Not sure I agree. Most revolutionary ideas are unappealing when first presented. The world thought Walt Disney was crazy for making a feature cartoon (Snow White) that went on to be one of the most profitable movies in history. Even after that, they thought he was nuts for starting a theme park.
Henry Ford once quipped, "If I had asked people what they wanted, they would have said, 'A faster horse.'"
Really? You think those guys got where they were by throwing out random ideas? The point is that with the right skills and chutzpah, solo founders can make it.
