I have run interviews for years where the feedback disappears into a form nobody opens again. Here it decides whether somebody gets the certificate. You write it differently when that is true.

I have a demanding day job. I do this on the evenings I want to and skip the ones I do not, and nobody has ever chased me about it.

What I did not expect was the arguing. Reviewers here push back on how a topic should be taught, not just on whether the code runs.

I sat down to write a lesson on something I use every week and found three things I could not properly explain. Fixing that in myself was worth more than the hour it took.

Nothing I write goes live until somebody else has read it. That has caught me being wrong more than once, which is exactly why I trust what is already on here.
