The presentation of an idea expressed with correct punctuation, grammer, spelling and proper word usage allows for the idea itself to be thought of without the distractions that improper use affords.
Simplified: By the time I had struggled through reading your suggestion I had already decided not to reply about the subject you chose. If you have a great idea that is ignorantly articulated, you may expect people to dismiss your idea because of that alone. People will assume that your idea has diminished value if they think you are ignorant.
Yes, I know this is harsh.
