"Send feedback" or "share feedback"? Or something else?

I am designing a feedback box that would be accessed by the user through the "Tell us what you think!" button in the bottom-right corner of the page. I am now wondering about the verb that should be on the button under the comment space. My box will be a free-form, not a list-of-questions.

So is either one of those expressions better considering precision as of what it does? Send feedback or share feedback? I just thought that maybe "Share" is too much associated with social media, so some users can get defensive or abandon the feedback form due to this reflection.
