I've now switched from using HTML4 to XHTML 1.1 in an attempt to improve compatiblity with older browsers. I personally would you advice you to do the same if you have a website, it shouldn't be too much work. The difference between HTML and XHTML is that everything needs to have a closing tag.

If you want to validate your website against XHTML, you can use validator.w3.org. I also tested my website against Dillo, which is a very minimalistic web browser, it also tells you have about any errors with parsing.

Also debating about changing the style of this website, as it's quite bloated with custom fonts and a background image.
