This week YouTube has unveiled a new version its YouTube Mobile website (m.youtube.com) specially meant for HTML5-capable browsers such as the iPhone's Safari and those on Android-based phones.

"[The update] incorporates the features and functionality you've come to expect from the .com site, like search query suggestions, the options to create playlists, the ability to designate 'favorite,' 'like' or 'unlike' videos directly from your device," YouTube product manager Andrey Doronichev writes in a introductory blog post.

In addition, Doronichev wrote, "It's really fast."

The reason for the focus on upgrading the YouTue Mobile experience is simple: the web is going mobile. "YouTube Mobile now receives more than 100 million video playbacks a day," writes Doronichev. "This is roughly the number of daily playbacks that YouTube.com was streaming when we joined forces with Google in 2006."

While HTML5 was not mentioned in the blog post TechCrunch notes that the updated YouTube Mobile "uses plenty of HTML5 features, including the video tag."
