If you had simply not uppercased this comment, it would be snarky but useful. Instead, it reads like an assault; it's the kind of comment a reader looks at and knows they can't use as the basis of a civil discussion.

Yeah, I figured that after I posted it. Oh well. (I'm used to using all caps on other mediums when I want to express meta-language/ideas and not natural speech, but I forgot that anything on HN that doesn't look 'respectable' gets downvoted quicker than INSERT JOKE NOBODY ON HN WILL LIKE)

It's a guideline on HN. For emphasis, use asterisks, and your text will be bolded.
