Semantics just means to give something meaning. Presentation semantics (http://en.wikipedia.org/wiki/Presentation_semantics) are just marking up the data to declare your intent for how you would like it to be presented.
> As I said, I don't believe this is an appropriate approach for a medium which has no absolute, definitive interpretation. A website isn't how it looks, because how it looks will differ depending on how you access it. The only absolute truth when talking about websites is the semantic purpose of the markup underlying it, because purpose is universal: a navigation element is a navigation element regardless of whether it's being displayed on a TV, a desktop browser, a smartphone, or being read out by a screen reader.
A HTML document is just text. Technically adding links, particularly navigation, is just presentation markup. As you said, it's up to the interpreter to make sense of that markup. The basis of your argument is that presentational markup is bad though, so I'm left unconvinced here.
> Changing how you structure the CSS in your application based on the whims of people whose area of expertise isn't CSS sounds like a nightmare scenario to me. If you're bootstrapping with a small team I can understand wanting to have everyone being able to contribute, but you should also be able to recognise what the limitations of their skills are. In the example you give, I would be using my web developer tools / inspector etc. to find out the origin of the erroneous property. If you're using a preprocessor there are source maps that can help with identifying how a rule was built. I certainly wouldn't conclude it's easier to use a presentational class name just so that my CTO could understand the code.
I'm concluding that presentational class names are easier to fix for the regular small changes that come down the pipe in our project. Even if you're regularly making big presentational changes to your entire site, then you'd need something a little more abstract, like using a class to declare an element as a button instead of the direct color it should be, but like I'm said, the argument against presentation markup is still unconvincing in the face of simple maintenance.

HTML is HyperText markup language. Hypertext is about links and references to other documents. Links are a first class citizen of a hypertext document. That's about function, not presentation.
