Britta, you raise a fascinating issue, namely about how to handle this with people who are already public. Ethically, I have to list this, especially as some of the learning may or may not be personal. However, I am happy to accomodate anything that generous participants want.
I had to navigate this before, when I explored autoethnographers who discussed their work. Let me just leave it that I was surprised how some of the reflective processing and learning through autoethnography never made it into the published research — a wonderful learning experience for me.
