Does anybody know how the internets work?

So, I mentioned the job I had in a previous post. I don't want to say that word (s-word) again for today. I think the strange thing is coming to realize that nobody at the company actually even really knew how the internet works. Apparently not one single employee even knew HTML. I was bewildered. But they DID rank. So....

Do people know how the internet works? I mean, I do and I just figured it out myself, so I assume there are thousands of people everywhere who went to school for this who must know more than me, right? I know my HTML CSS PHP and MySQL and I more or less know how to make the internets, is this actually a valuable or rare skill?

Seeing that company thrive with no comprehension of the technology made me feel like it might be a rare skill, but may not really be necessary... Anybody know?

Now to be irritatingly un-relating (yet so right on topic). Here be my links from delicious. Deal with it!
