ETA:
Also, if you're going to edit your responses after you post them, I recommend using the `delay` feature in your HN settings, or adding an addendum section like I'm doing here, as it's a little unfair to people responding to you to make undisclosed changes so it looks like people responding to you aren't responding to all your points. I'm not saying you're being dishonest, I'm just saying that it feels a little unfair to responders.
