I don't want to get into a long discussion about this (because that would be thoroughly defeating the point), but to respond to alex and Pixelarge to say that the core development team is definitely open to feedback and input from everyone in the community. The problem is that much of the feedback is given in angry blog post comments (primarily on WP Tavern). I don't know about you, but if I'm a core developer for a product then I am highly unlikely to listen to angry and insulting comments about the way we do things.

The point of my blog post that was linked in this article, was to show people where the appropriate channels for feedback are located so you can make sure your voice is heard. So if you have ideas or input then please go to the correct channels (they exist for a reason) instead of commenting elsewhere and then wondering why you aren't being heard.

So the moral of the story is to use the right channels instead of the wrong ones and be respectful when you communicate your opinions :)
