 * Are you writing xHTML or HTML? If you write xHTML, then a linebreak is `<br /
   >`, but in regular HTML, you get `<br>`… so that may be a reason.
 * scratch that… took a look at your code… you have to use all lowercase in your
   markup when you use an XHTML doctype.
 * as for the del tags, I didn’t look too deeply, but from the validator’s notes,
   it may just be some quotes left open somewhere?

 * When I use the `<del></del>` in the title it doesn’t like it either, but it says
   it is valid. It seems it does not expect to see code in the title, but I love
   the strike through myself.
