One of my least favorite things is a web page that says "email us", when it really only offers you a form to fill out.
I've got a selection of email clients, all of which I find preferable to your web form. If you suggest that I can email you, give me an email address, and I can do the rest. If you're not giving me an email address, perhaps you could reword your page. "Type your comments here!" or "This is a form that will accept 200 characters worth of your ideas!"
