Whew. Just managed to get the index, news and products pages of the latest Project Krystal build (version 0.9 RC1) to validate under the XHTML 1.0 Transitional standard. I think it's a very good idea to validate, as it helps to ensure that your site works on as many platforms, browsers and operating systems as possible. I like, use and try to spread Firefox, but that doesn't mean I'm going to lock IE users out of my site or irritate them with a browser-specific popup or something. If they want to use a browser with more holes in it than Swiss cheese, then that's their choice.
