An observation about Designers versus Developers

Apparently I've been sort of ignoring an increased friction between Drupal designers and developers the last few days. Not that I don't know it's there, I'm right up in the forefront of that friction, feeling fairly regularly told what to do by people who I feel aren't fully informed as to why I created things the way I did. And most often I don't react well to this, and I cause more friction than I really should. But this isn't just about me. That friction is there and it's all around.
