title: Is XHTML compliance pointless?
body: <p>I'm building a site right now, so far I've painfully forced everything to be compliant and it looks pretty much the same across browsers. However, I'm starting to implement some third party/free javascripts which do things like add attributes (eg. order=2). I could work around this but it's a pain, and I'm starting to lose my principals of making sure everything is valid. Really, is there any point to working around something like this? I got the HTMLValidator plugin for firefox, and looking at most major sites (including this one, google, etc.), they aren't valid XHTML or HTML.</p>
