I think this post about personal branding is onto something.
Sending thank you cards is so important. I did this in the zygote days of this website to most of the people who helped me out and there are still thank yous that I need to send.
I think sending a thank you card to someone who interviewed you or helped you in any way is definitely a way of being a more personable candidate.
It is good personal PR which is something we could all look at more for ourselves.
