People sometimes ask "do you ever hear back from journalists whose articles on Bitcoin you challenge? Happily yes: ~10% of the time there is a significant revisions or a retraction (like this one I received today)/ On many occasions, I don't get a response, but the outlet stops writing negatively, and on 2 occasions the Media outlet has written to let me know they are fundamentally changing their Bitcoin mining coverage based on the information I've supplied.(Daniel Batten)
