Actually, this makes me think... I don't think I've ever given feedback on an open source project.
Maybe I, as someone horrified by Heather Arthur's story, have some sort of ethical obligation to provide constructive and helpful feedback to people. I'm not a great programmer, but I've been at this for long enough to have some useful opinions.
Open invitation for my fellow HN community members: point me at a repo and I'll try to say something actually helpful.
