ShowHN: Are HTML5 canvas UI's the way of the future?

I wanted to show HN my latest work, www.graffitidrop.com, and get some feedback from the community. 99% of the interaction on the site is through HTML5 canvas. I found that HTML5 canvas allowed for a more fluid interface, so I thought I'd pose the question "are HTML5 canvas based UI's the way of the future?".

Ummm they are just like using flash. No standards, no w3c, an interface stuck in a box which happens to sit on your site.
