The asymmetry of the situation strikes me. Where a company which decides not to hire someone can only say "we're not following through with your application at this moment" out of fear of litigation, the candidate can freely comment on his decision to not take the job.
It would be nice when companies were able to do the same.
I live in the UK, and have gotten good feedback from jobs I didn't get. Even though they were rejections, I often agreed with their points and choices. I liked the companies more as a result. If I had solicited, and then received this email, I would be very grateful - this kind of opinion must be very difficult to find.
