While I agree that HTML is acceptable, I personally have never seen how it's better than XHTML. XHTML definitely makes life easier for the browser vendors, and if they spend less time debugging their HTML parsing engines then they can spend more time adding CSS3 support! From the coder's perspective, is it really that much harder to write XHTML than plain HTML? Personally I find writing HTML more of a hassle, but that's just because I use XHTML on a daily basis...
