HTML5 attempts to solve issues found in previous iterations of HTML. It is a joint effort between the W3C HTML WG and the WHATWG which is estimated to be finished by 2012, but whose functionalities we may start enjoying pretty soon – Microsoft has already started implementing parts of HTML5 in IE8.
HTML4 was designed in 1999, without taking into account tabs, RSS, flash and HD video – SGML, XML, XForms, RSS, CSS even AJAX has been the main focus until now.
But if you’re not a programmer geek, how can all this help you out?
A cleanly organized page which essentially follows a “DOM” tree will be more easily crawled, and the content within more easily parsed and indexed by a spider. Are you searching a concrete date? A determined video or audio format? Are you searching an article, a definition or a conversation?
No more plug-ins
Who has tried to watch a video and said “hey I can’t see it”. “Shit, the codecs. How was that pack that they told me that…?”
As evidenced by various Flash-based media players, authors are interested in providing their own custom-designed user interfaces for video viewing, which generally allow users to play, pause, stop, seek, and adjust volume.
Easier web structure
If you want a new web page, you should know that HTML 5 introduces a whole set of new elements that make it much easier to structure pages.
