Cargo Cult Programming
Reading the comments to the latest WTF I’ve just found out that, when it comes to HTML, I am guilty of cargo cult programming, in particular the following is a perfectly valid HTML document
<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01//EN" "http://www.w3.org/TR/html4/strict.dtd">
<title>foo</title>
<p>foo</p>
You can try it for yourself at http://validator.w3.org/. Personally I still think the <html>, <head> and <body> tags are good style.
