It takes a certain kind of a skill set and experience to be able to translate this "consumer view" into something that can be acted upon by a developer.
Sure, the skill set can be developed, the knowledge (about software development, the available technologies, and having an idea of what is and isn't feasible in the first place) can be built up, and the experience (communicating with developers) can be accrued, but that really stops a lot of people from even thinking of contributing.
Perhaps a subset of the (open-source) community can help in developing these (skills, knowledge, experience) among interested people. Teach people how to look for issues, bugs, or come up with feature requests; teach them how to put these into a form that's easily understood and appreciated by the developers, and finally, teach them how to communicate with developers without losing the "non-techie user POV" which makes their feedback valuable in the first place.
IDK though, having read what I've just written, it seems to be quite a task.
