One final note: say the obvious. Sometimes we might feel that something is obviously good or obviously wrong, and so we don’t say it. Or sometimes we might have a doubt that we don’t express because the question might sound stupid. Say it—that’s okay. You might have to reword it a little bit to make the reader feel more comfortable, but don’t hold it back. Good feedback is transparent, even when it may be obvious.~ Erin Casali from, https://alistapart.com/article/async-design-critique-giving-feedback/
If you are a human, and particularly if you ever interact with other humans, I think you’ll like this article by Casali. I’m a level-100 Technology Wizard with a sub-specialization in Explaining Things, and I found several insighs—e.g., “timing + attitude + form = respectful feedback”—that improved my integration of what I know about feedback.
