The newest versions of all major browsers support most HTML5 features. It's open standard. It won't replace Flash. New security threats loom. As with any new technology, hackers will be looking for ways HTML5 can be misused. What's important is that HTML's features - such as the aforementioned geolocation, web apps, video and graphics can be used now, provided your browser supports them.
You've probably got one already. Firefox generally supports the widest selection of HTML5 features, with Chrome and Safari following shortly afterwards, but as we said HTML5 is an evolving standard and the latest versions of each browser more than cover the basics.

Consider the kind of processing a search spider has to do get the title, description etc if a pages markup is badly malformed — Joseph Earl.
Joseph, legal obligation to accessibility?! If that were true half the sites on the net would get sued. People who are going to write valid markup will write valid markup. Those that won't, won't. The choice of markup language isn't going to change that. Elizabeth: legal obligation is correct — in the UK, the Disability Discrimination Act applies to websites, and in Australia the website for the Sydney Olympics got sued for not being accessible.

I think the main problem is, it still seems like a mysterious creature to many.

With new semantic tags screen readers can better examine the HTML document and create a better experience for those who use them. Your media tags just become these nasty, huge chunks of confusing code segments.
But what about all those parameters like height, width and autoplay? Pretty simple right? No more cutting and pasting some long unreadable line of code and no more dirty head tags filled with doctype attributes. You can simply and easily type it out and be happy. The really great thing about it though, beyond the simplicity, is that it works in every browser clear back to the dreaded IE6. If you are passionate about simple, elegant, easy to read code then HTML5 is the beast for you.

I know, that is a pretty crazy assumption and some of your are probably thinking — mobile is just a fad… right. Mobile devices are taking over the world. The adoption of mobile devices continues to grow very rapidly and this means that more and more users will be using their mobile browsers to view your web site or application. HTML5 is the most mobile ready tool for developing mobile sites and apps.
With Adobe announcing the death of mobile Flash, you will now count on HTML5 to do your mobile web application development. Mobile browsers have fully adopted HTML5 so creating mobile ready projects is as easy as designing and constructing for their smaller touch screen displays — hence the popularity of Responsive Design. There are some great meta tags that also allow you to optimize for mobile:. So, start using it right now, whether you are just simplifying and making your markup more semantic OR you are gonna build some sick new mobile game that will take over the world — who knows, maybe you can start selling stuffed animal versions of your gaming characters too.
