+1 I agree that user feedback/ideas on improvements and simply knowing what other people value is a key thing, at least for me. My open source projects consist of about 70 GitHub repos for things that interested me. For things that really interest me, I work them into my free (optionally people can pay me) eBooks[1]. Sometimes readers make really good suggestions for improvements which I very much appreciate. I also use the fraction of books voluntarily paid for as a key signal of what people value so I tend to expand those books with new examples and material. BTW, off topic, but I am starting a long process of converting all of my eBooks to a very permissive Creative Commons license so the material can be re-purposed, even commercially, by other people of companies.
