Mike Malone has recently posted a great article which could be useful to most web developers asking what the hell is HTML5 syntax like or how different will XHTML2 be.. or even better, when the hell they’re gonna be out and official?
As for me, I’m still thinking and analyzing. One thing is for sure. HTML4, which is still used, is over 10 years old. And W3C is really getting annoying with delay as I hope my children will not use it. I’m starting a wast research to find major advantages / disadvantages of both standards, but till then, read more about it at XHTML 2 vs. HTML 5 article.
