At this point, it seems like the tech world has pretty much decided that the future of the web lies in HTML5. It might be for this reason that the World Wide Web Consortium (W3C) decided that the standard needed a heroic new identity - and this is what they managed to come up with.
The logo is described as "[standing] strong and true, resilient and universal as the markup you write. It shines as bright and as bold as the forward-thinking, dedicated web developers you are. It's the standard's standard, a pennant for progress".
The idea is to provide a single visual identity that brings together the broad set of technologies that fall under the general HTML5 umbrella. The Consortium is hoping that the community will get behind and support the new branding and if all goes well it could be adopted as the official logo some time later this quarter.
Sites that are already using the standard are being encouraged to adopt the logo and it's been licensed under Creative Commons 3.0 By, meaning that anyone can modify it to suit their needs. There's also a handy badge builder on the official logo page that can be used to show off which HTML5 technologies a site uses.
More details on both HTML5 and the new branding can be found on the logo launch page or in the FAQ on W3C's site. After you've checked that out, why not let us know what you think of the language's new look in the HEXUS.community.
