Lionhearted, it has struck me how often you live up to your name; but on that one isolated occasion, you shamed it.
I was thinking it would be hard for you to make amends. Removing the submission from HN is an excellent start, but it's still on your blog: http://www.sebastianmarshall.com/?p=251 I don't think Patrick should have to do or say a single thing in order for you do the right thing. If he asks you to restore it, then do so.
This isn't about your reputation.
EDIT like edw519, I (FWIW) also want you to stick around. It's OK to make mistakes, provided you fix them. So... fix it, quick! Of course I can't speak for Patrick, but remember what happened with _why.
