When reading articles on your page, it is frustrating to move to the next line and be forced to scroll around the feedback button. Add a margin to the left hand side of the page so that this doesn't ruin user experience. While the axiom of content being king may rule the day, site visitor stickiness depends on usability of the site.

I'm glad you have a feedback page and the site is very well put together. My suggestion is make the feedback page consistent with the same header and footer so it doesn't look like a page I came to when I typed in a domain wrong. Two thumbs up on my first impression. Keep up the good work.
