I often mis-apply slack/markdown formatting.

Instead, now I will less often mis-apply markdown formatting to hacker news.

Thank you!

And this isn't "wildly off-topic", by the way. This is "extremely germane to what I said, but addresses something other than the specific point I was trying to say."

Doesn't make it not helpful. In fact, I bet there are many situations where this kind of feedback is more (I almost wrongly-formatted that!) helpful than addressing the comment directly.

You, dear internet stranger, have taught me something. Thank you!
