"The web is constantly evolving. New and innovative websites are being created every day, pushing the boundaries of HTML in every direction. HTML 4 has been around for nearly a decade now, and publishers seeking new techniques to provide enhanced functionality are being held back by the constraints of the language and browsers. To give authors more flexibility and interoperability, and enable more interactive and exciting websites and applications, HTML 5 introduces and enhances a wide range of features including form controls, APIs, multimedia, structure, and semantics."

Without XML analness well get the nonstandard compliant mess of html 4. I like the XHTML approach "if it's not correct you don't have to render it". This will force tool vendors to make sure their editors generate proper tags and will make parsing html for its data much easier.

It depends on your design goals and the audience in which you want to interact with:
1.4.1. HTML vs XHTML
This section is non-normative.
This specification defines an abstract language for describing documents and applications, and some APIs for interacting with in-memory representations of resources that use this language.
The in-memory representation is known as "DOM5 HTML", or "the DOM" for short.
There are various concrete syntaxes that can be used to transmit resources that use this abstract language, two of which are defined in this specification.
The first such concrete syntax is "HTML5". This is the format recommended for most authors. It is compatible with all legacy Web browsers. If a document is transmitted with the MIME type text/html, then it will be processed as an "HTML5" document by Web browsers.
The second concrete syntax uses XML, and is known as "XHTML5". When a document is transmitted with an XML MIME type, such as application/xhtml+xml, then it is processed by an XML processor by Web browsers, and treated as an "XHTML5" document. Generally speaking, authors are discouraged from trying to use XML on the Web, because XML has much stricter syntax rules than the "HTML5" variant described above, and is relatively newer and therefore less mature.
The "DOM5 HTML", "HTML5", and "XHTML5" representations cannot all represent the same content. For example, namespaces cannot be represented using "HTML5", but they are supported in "DOM5 HTML" and "XHTML5". Similarly, documents that use the noscript feature can be represented using "HTML5", but cannot be represented with "XHTML5" and "DOM5 HTML". Comments that contain the string "-->" can be represented in "DOM5 HTML" but not in "HTML5" and "XHTML5". And so forth.
"Sony gave the PS4 50% more raw shader performance, plain and simple (768 SPs @ 800MHz vs. 1152 SPs & 800MHz). Unlike last generation, you don't need to be some sort of Jedi to extract the PS4's potential here. The Xbox One and PS4 architectures are quite similar, Sony just has more hardware under the hood. Weâll have to wait and see how this hardware delta gets exposed in games over time, but the gap is definitely there. The funny thing about game consoles is that itâs usually the lowest common denominator that determines the bulk of the experience across all platforms. On the plus side, the Xbox One should enjoy better power/thermal characteristics compared to the PlayStation 4. Even compared to the Xbox 360 we should see improvement in many use cases thanks to modern power management techniques." AnandTech does its usual in-depth thing.
"The Verge has learned that HTC's Chief Product Officer, Kouji Kodera, left the company last week. Kodera was responsible for HTC's overall product strategy, which makes the departure especially notable on the heels of the global launch of the make-or-break One. It's not just Kodera. In the past three-odd months, HTC has lost a number of employees in rapid succession." I really hope HTC pulls it together.
"It is with huge pleasure that the Debian GNU/Hurd team announces the release of Debian GNU/Hurd 2013. This is a snapshot of Debian 'sid' at the time of the Debian 'wheezy' release (May 2013), so it is mostly based on the same sources. It is not an official Debian release, but it is an official Debian GNU/Hurd port release." Important note: 75% of Debian packages are supported bu Debian GNU/Hurd. Impressive.
"The first killer app was VisiCalc. This early spreadsheet turned the Apple II from a hobbyist toy to a business computer. VisiCalc came with room for improvement, though. In addition, a new architecture and operating system, the Intel-based IBM PC and MS-DOS, also needed a spreadsheet to be taken seriously. That spreadsheet, released in early 1983, would be Lotus 1-2-3, and it would change the world. It became the PC's killer app, and the world would never be the same. On May 14, IBM quietly announced the end of the road for 1-2-3, along with Lotus Organizer and the Lotus SmartSuite office suite. Lotus 1-2-3's day is done." Impressive 30 year run.
"There's a disconnect between how Apple CEO Tim Cook sees his company's tax strategies and how some members of the US Senate view it. That became clearer than ever today after Cook and two other Apple executives testified before Congress, explaining why they're holding most of their international income in Irish subsidiaries like Apple Operations International, which declare no tax residency anywhere in the world. AOI hasn't filed a tax return anywhere in the world for the last five years, yet it earned $30 billion in income from 2009 to 2012, according to a Senate report released yesterday." Just because something is legal, doesn't mean it's just. Apple, Google, Microsoft, and many more - these companies might not be breaking any laws, but it's obvious to anyone that what they are doing is scummy.
The new WebKit Opera for Android has been released. "Opera 14 for Android is built on top of Chromium 26, with a total overhaul of the UI in native code, making it fit well with the latest Android design guidelines. Go get the build from Google Play or point your browser to m.opera.com, and give it a spin!"
The Verge pointed me to a blog post by Leap Motion - which reveals how their Kinect-like motion control works with Windows 8. "From the second you plug in your Leap Motion Controller, you'll be able to browse the web and interact with your computer just by moving your hands and fingers in the air. With Leap Motion technology and Windows, you can do everything that's possible with multi-touch inputs - without actually touching anything. This also means that existing applications in Windows 7 and 8 will respond to your natural hand and finger movements. Soon, we'll show you how Leap Motion will work with Mac OS X." Quite cool.PocketNow interviews Marc Dillon, and there's an interesting note about why Jolla is keeping the display properties under wraps: "We're leaving some of those details out because we do understand that there are a lot of really big players in the market and they tend to take certain components in the market and dominate them. We created the ability to actually be able to run Sailfish on multiple hardware displays and be able to swap components, so this is part of the demand and supply planning phase. We are committed to this industrial design which is a 4.5-inch display, an 8 megapixel camera on the back and a front-facing camera at the front, and the exact specs of the display we'll provide when we're close to delivery." Something you rarely hear anything about.
"This is my NeXTstation Turbo Color booting the Mac System 7.1 Operating System using a hardware add-on called 'Daydream'. The Daydream has a Mac ROM and a few custom ICs in it and hooked up to the NeXTs DSP port. Turns your NeXT into a full fledged 68k powered Mac." So cool.
"The NetBSD Project is pleased to announce NetBSD 6.1, the first feature update of the NetBSD 6 release branch. It represents a selected subset of fixes deemed important for security or stability reasons, as well as new features and enhancements. Please note that all fixes in the prior security/bugfix updates (NetBSD 6.0.1 and 6.0.2) are also in 6.1."

2.5. Evolution Not Revolution
Revolutions sometimes change the world to the better. Most often, however, it is better to evolve an existing design rather than throwing it away. This way, authors don't have to learn new models and content will live longer. Specifically, this means that one should prefer to design features so that old content can take advantage of new features without having to make unrelated changes. And implementations should be able to add new features to existing code, rather than having to develop whole separate modes.
Switching to XML syntax requires a global change, so continue supporting classic HTML syntax as well.
Anyone who uses XML will most certainly use XML complaint syntax that is first citizen for HTML 5.
