Asking people for their opinion on anything (in my case, it's writing) is an art. Not everyone's opinion is worth listening to. If you throw it out to the general public, you'll get a lot of stupid ones. It's better to pick a few people you respect, who are not uncritical lovers of your work. But you need to do that. As the creator, you have a blindness that it's impossible to get past all by yourself.
Speak with domain experts (people who use, provide, and repair the product or service) because it is faster than learning about the product yourself. - IDEO
