I know neither you nor Andy in person. But from reading Andy online, I get the impression that he is bright, talented, and kind. From reading you, I get the impression of someone bright, talented, and immature. I value your technical contributions here, but at times fear your overall impact on the site.
Banning you from a project is not hypocritical on his part -- it's exactly what he's talking about. He feels, rightly or wrongly, that it's better to remove the source of incivility than to put up with it.

No, I don't care for iPads either. My fear is that HN is a wonderful but fragile community.

I like that civil public discussion is still possible here, and want to keep it that way.
