Large eCommerce site: Is it time for HTML5?

Question

I currently work for a large company and I design for their high-traffic ecommerce website. We support tens-of-thousands of users across a variety of browsers. Our current browser stats point to most people using either Firefox 3+ and IE8. There are about 5% of users still on IE6.

Is it time to start coding for the future and impliment HTML5 across the site? Is it a responsible thing to do or should I wait a year for people to upgrade to better supporting browsers?

Thank you.

HTML5 isn't one specific thing. You can start using it even in browsers that have no idea what HTML5 is. If you just start using some of the extra tags or form types, they degrade perfectly into standard elements in older browsers. Video needs a Flash fallback anyway. The advanced scripting features all need fallbacks for non-supporting browsers anyway, or must only add non-essential functionality.

In short, sure, start using HTML5 techniques now to provide advantages for cutting-edge browsers, just make sure it all degrades nicely in older browsers.
