The W3C is encouraging vendors, Web-site/app developers and others to use the logo on their sites, t-shirts and stickers to raise the visibility of HTML5. If the community embraces the logo, W3C "will adopt it as its own official logo for HTML5 in the first quarter of 2011," the FAQ page said.
Microsoft is planning to promote the logo immediately on "the major Microsoft HTML5 properties," including the IE 9 test drive site and its associated Beauty of the Web site. The W3C site lists html5rocks.com, Modernizr and "a host of other sites and apps" as being early advocates for the new logo and/or its component parts.
"The logo program is an important step forward to raise awareness that parts of HTML5 are being used by real sites today. While there is still a lot of discussion about when HTML5 will be ready, the reality is that HTML5 consists of a broad range of technologies. Some are very stable, and some are in early working drafts and changing rapidly. The stable parts of HTML5 can safely be used today," said a Microsoft spokesperson via e-mail.
