Not to be that guy but regardless is the correct form. Irregardless is considered as non-standard or incorrect. But if you do know this, please don't mind this nitpick.
I smiled reading this comment.
If you make a mistake and someone corrects you, I assume you also try to learn from it.
On HN, I believe that people are trying to make a positive contribution when the post, and while correcting people on the internet can seem pedantic, I take it to be a positive contribution and an opportunity to learn something.
Edit: too old to edit! But still, thanks for the info.
