Web designers should do their own HTML/CSS

Are there actually designers who don't have to get their hands dirty with HTML/CSS? I've never met 1 in my 8 years of designing and building sites. Sounds like a nice gig.
I think the confusion comes from referring to the person who does the mockups as a "web designer." I have yet to meet a person with that title who does not know HTML or CSS. The people who don't get their hands dirty with the coding are usually referred to as just graphic designers.
If you're handing your HTML/CSS to a "HTML monkey" and they don't get the "it" stuff right (as opposed to the "around" stuff), then they are a BAD HTML/CSS coder. Period.
The baseline HTML/CSS coder, in my mind, should be able to get pixel perfect (or very close to pixel perfect) designs implemented with cross browser compatilibity (at least IE6 and Mozilla).
HTML/CSS coding is in most cases a solved problem. If you have the man power to segment design from the actual implementation, then all the power to you. It'll probably be more efficient that way. Where I work, we don't have that luxury, and we all have to do a bit of everything.
In summary, I find 37signals to be full of shit.
They are just stating why they are doing what they are doing. Good information if you want to make use of it.
Their blog posts just come across as a bit partisan and dismissive on a lot of issues. Even when they're making good points, as in this post.
