This isn't about "web development discipline," it is a rant about how people should support IE6 cheerfully, with the idea that it is normatively incorrect not to support it. Whether or not to support IE6 is reasonably a business decision based on your audience and resources for implementing. That balance shifts over time (note that we are not having this discussion about IE3, 4 or 5 any more). If you need to support IE6 then yes, support it from the beginning. If you don't need to, then don't. There is a valid role for advocacy and social pressure here, it is not writ from God that "thou shalt support IE6 even if it be costly with little benefit."
