I wanted to see what the general consensus is from SDN experts on contacting programs post interview season. I know the big no-no is to tell a place your ranking them first and then not following through. I am asking specifically because I had a few programs that I really like, but aren't #1, that told me to "keep in touch" or "let us know what your thinking" at the end of interview season. Although these programs aren't my number 1, they are high on my list, and I would hate to fall down on their rank lists if I don't contact them in some form. Any thoughts?
