Speaking as an introvert, that's certainly not my intent. But if the only way to share ideas is to do things that make me miserable, and the people who need to listen my ideas made it that way, they're clearly not interested. In most cases I have better things to do than fight uphill or shout into a void. It's probably a lot of stress for no benefit.

Ed: incidentally, suggestion boxes (mentioned nearby in the thread) are also probably not helpful. Absent strong evidence to the contrary, I assume those are ignored and don't bother.
