I agree with the positioning of the feedback tab. It's not so much that it is "out of place" but rather its just in a bad place at the moment. It's right between "stop sleeping through outages" and the big green sign up button. This is your headliner content, there should not be some flat rogue turned-sideways feedback tag conspicuously thrown over it.

As for the other points. Well this is clearly a 37 signals approach. If nothing else, it is good for SEO. I think most users will click on the video first anyway. So all the content acts to complement the video, which is a good thing.
