Siding With HTML over XHTML
I've never been a huge standards guy, but I liked this post, which led me to Beware of XHTML and The Mozilla Web Developer FAQ, which taken as a whole made me switch to HTML 4.0 over XHTML 1.0 transitional for a new project.
I will say though, "Beware of XHTML" seems a little harsh as a title, either standard you use, chances are the browser is going to compensate for any syntax mistakes you make anyway (the logical consequences of years of making syntax mistakes). And, html 4.0 and xhtml 1.1 are close enough in syntax that it would probably take ~20 minutes to switch between them if you did have to change standards.
In fact, the only thing syntax mistakes seem to do is make your site lose some cred from a small but very vocal standards minority.
