Pam, so you'd have V throw away credibility by looking like she doesn't care enough to write well? I can't be the only one who loses sight of the content when carelessness and sloppy writing shove themselves in my face.
I always find writers who say "my message is so important I'm above spelling and grammar" rather rude. If you want me to respect your time and energy enough to read and act on what you say, respect my time and energy by correcting the grade-school mistakes and write coherently so I don't have to spend so much time struggling to figure out what you intended to say that I run out of time to think about and maybe take action on what you're talking about.
