I've been going through the comments on previous posts. I think one of the biggest issues with the article is the title. It seems to act as an anchor for a lot of people to the point where they'll argue against things that aren't in the article, just implied by the title (without context). So there'll be people arguing that she doesn't want to validate at all and just wants to parse, when really the article is about where you validate your data (and what you do with the result). It is not about getting rid of all validation.
