OK actually thinking about it I have worked at one organization where they did listen, other than startups of course, but even in those the people who had power to implement things tended to consider the ideas of non-programmers more important, which maybe they were.

Not sure how it is doing now about listening to programmers because it was sold off by the parent company and then became really successful and grew a lot, so it is essentially a different company.

I have a feeling it is less likely to listen to things now though.
