Mark said it on Friday: We absolutely adore HTML5, and the prospect of delivering great-quality, speedy video directly in your browser without using Flash has us thinking unpure thoughts here at 23. (There are plenty of reasons why we’re not quite there yet. I won’t dive into the details, but if you want me to drag you in to that vortex, just ask…)

We’ve actually used HTML <video> for a while in the mobile version of 23 Video, but today we’re beginning to test wider adoption of the possibilities. To do this testing, we’ve enabled HTML5 video on a few sites including Reboot and Madbio. In practice this means that you will be able to play video in most modern browsers and mobile devices even if there’s no Flash installed — this includes Safari, Google Chrome and the iPad.

We’ll be beta testing these new features for a few weeks before rolling it out to all customers — but if you want iPad and HTML5 video support now, drop us a mail or ping us on Twitter.

You can already make your 23 Video site run on iPhone, Android and a whole bunch of other mobile phones that support H.264 encoded video, but we’ve just got our hands on a rather promising device…

We present to you: Obligatory Blurry Pic Of Beta Service Running On Cool Hardware:

We don’t have a timeframe on when this will be wider available, but watch this space, and you’ll be the first to know.

Yes, the inevitable iPad post has hit the 23 blog.

Obviously we’re very excited about the iPad – not only because Apple introduced a new product (we are dedicated, naïve fanboys here at the office), but because the shape of the device itself is interesting for us. After it was introduced, our internal “digital watercooler” – Yammer – was red hot with posts from 23-employees discussing which version of the iPad would be the best purchase. Not if we should buy it, but which one.

The “tagline” of 23 is “The Visual Sharing Company”. We like things that are communicated visually and our products reflect that. We already have tight integration between 23 Video and other platforms such as podcasting through iTunes and RSS, directory listing in Boxee and an iPhone/Android-optimized site (try accessing http://video.reboot.dk on your iPhone/Android). The integration with other platforms is essential for sharing video with customers who want to access the content in their own way.

With the introduction of the iPad on Wednesday, we saw a new potential for our customers to reach out and create compelling experiences for their customers. After all, video already looks good on the iPhone, but it will look absolute stunning on the iPad with a screen size four times larger than the iPhone.

So tell us, what are some of the things you look forward to seeing the most on the iPad?
