That is a very awesome article, sadly enough I've been to all those sites and complained for those very reasons. The only thing I think could be changed is don't open links in new windows. I that ability in order to open things such as a chat room or a forum into a new window while leaving the user capable of reading the rest of the site.
<?php echo "Hello World"; ?>
<html><head><title>Hello World</title></head><body><p>Hello World</p></body></html>
