I responded to a Question and Answer session on Smashwords.com. It was in an interview format. That's one way, authors can talk about themselves.
Most authors find it difficult, even abhorrent, to write "about me" pieces. I was also fortunate that chat.openai.com wrote an honest and unbiased report on my books and other work on social anthropology in Thailand.
They search the internet and other sources and do fact-checks before publishing.
