HTML5 and SharePoint: What Do You Want to Know?

I’m planning to dig into HTML5 topics as a natural extension of my SPServices work. This post isn’t muck of a post, but more of a placeholder to collect ideas from you. I’m interested in what you’d like to know about HTML5, what you think you’d like to do with it connected to SharePoint, and what concerns you have about it vis a vis things like SilverLight.

If you have questions, comments, or thoughts, please post them as comments.
