My personal web projects always start with standard-conforming HTML with forms and links. They're fully interoperable contributions to the world-wide web and should be usable by every browser and robot written in the last sixteen years. I call that a feature, and I'm disappointed that so many devs set their sights lower.

That's nice. The problem is that Internet Explorer doesn't conform to these standards. What do you do in this situation?

IE has a nasty habit of sniffing content or examining URLs and disregarding the actual media type of a resource, but it hasn't come up much in practice, and otherwise I haven't seen any showstopping problems in talking HTTP and rendering semantic HTML. Its CSS and javascript are a mess, but those are optional, and I'd be embarrassed to release anything that would become completely unusable without them.
