My feedback was to not put feedback scripts on your website.

Seriously, that crap is annoying. Even after providing feedback, the button won't go away. I ended up having to manually block the script and its css with AdBlockPlus to get rid of it.

If you want people to give you feedback, don't be intrusive about it. Send out an email with a link to a page where you can give feedback or something. Overlay scripts on every page do nothing but annoy customers.
