I agree. I'd like a "bad language" filter that corrects poor spelling, uncapitalized "i" for first person singular pronouns, and cleans up your grammar.
Where did you get this "selective hearing"? That option was not offered to me when my ears were installed. I think I'd like to use it in business meetings to help block out words like "proactive", "customer-focused", "shareholder value", and "team member".
