I was wondering if it it too early to use HTML5 for a production site. Should I rather wait 6-12 months until users have updated to compatible html5 browsers?
This leads me to,
Depends on the HTML5 features you use. In general only Chrome and Safari (webkit-based browsers) support most of HTML5, the other browsers including IE8 and Firefox lack support for various features. See http://www.scriptol.com/xml/html-5-browsers.php
