I think that's a fantastic way of thinking about it. Businesses don't win custom by doing totally unique things, but by doing common things in a way that is local/prettier/cheaper/easier/in a language you speak/on a device you own.

I think you've changed the way I'll look for "the idea". Not something new, but a problem I can solve, that people have and that scales, that other people like me don't want to touch.

One of the best comments I've read on HN, especially for stressing the complexity of why a product works. Thanks Daniel.
