Semantic we stand Divitis we fall - Web design teacher says thanks

Semantic we stand Divitis we fall. This meme has been runing around on twitter for the last day or so. So what is semantic code? Aquick google search bring up a Paul Boag blog from 2005 boagworld.com/technology/semantic-code-what-why-how/   Thanks Paul, I listen to and recomend your "classic" (old) boagworld podcasts and I follow you on trwitter (you are prolific). Interesting to note that this concept is as important now as it was 10 years ago. Tomorrow we tackle Divitis. anybody have any suggestions?
