HTML 5 is still a draft specification.
Are you comfortable with a spec that may change, is not fully or even uniformly implemented across different browsers? If the answer is yes, then use it.
On my own personal site, which is also my development playground and it doesn't matter if a feature does not work I would certainly play with it.
For a professional site? Not until the spec is final, approved and well supported on the different browsers/platforms.
Personally I would say "go for it" get used to it - ready for the big roll out.
Professionally, wait! it isn't ready!
I personally agree with Oded. Check this useful site to see which features are implemented by actual browsers and make your informed decision:

PS This site heavily uses some html5 features, so it's viewable only with Firefox, Chrome or Safari.
I've started using HTML5 because of the HTML5 Shiv which is an HTML5 enabling script. Plus, I've had a couple of clients want it, to "future proof" their site.
CSS3, I use mainly to add styling that will make the site look better for Webkit/Firefox users.
About 40% of browsers support html5 and css3
