With Google and Apple strongly supporting HTML5 as the solution for rich applications for the Internet, it's become the buzzword of the month -- particularly after Google I/O. Given its hot currency, though, it's not surprising that the term is starting to become unhinged from reality. Already, we're starting to see job postings requiring "HTML5 experience," and people pointing to everything from simple JavaScript animations to CSS3 effects as examples of HTML5. Just as "AJAX" and "Web 2.0" became handy (and widely misused) shorthand for "next-generation" web development in the mid-2000's, HTML5 is now becoming the next overloaded term. And although there are many excellent resources out there describing details of HTML5, including the core specification itself, they are generally technical and many of them are now out of synch with the current state of the specs. So, I thought a primer on HTML5 might be in order.
