Argh! It’s not my fault, I was brainwashed as a child. I try to keep it down to just one space but I can’t help myself. I’m the victim here!

You did a great job in that comment, though :)

It's just how HTML is rendered, you'll never know whether OP used 1 or 2 spaces in that comment.

If you look at the comment through the Hacker News API, there's two spaces before the last sentence.

Although, the documentation says that field is HTML, so I'm not sure what to think.
