Learning HTML5

Renewed interest update! I'm beginning to poke around and properly learn HTML5 again, with some hands-on prototyping and the goal of building a mobile app. Here is my collection of links, please chime in with comments and suggestions...

1. Reading: HTML5 for Web Designers, Chapter 1 
2. Links: My HTML5 Delicious bookmarks (rather dated at this point) 
3. Examples: HTML5 Gallery sites 
4. Shiny: Website Example: Arcade Fire's The Wilderness Downtown 
5. Funny: Single use site Is HTML5 Ready Yet? 
6. Shiny: Check out The Expressive Web feature exploration (Thx 2 Maxx)
7. Javascript: jQuery Mobile (how popular is this one?) 
8. IBMish: New mobile dev community and dev feature pack
9. Apps: PhoneGap for building iOS / Android apps for app stores with HTML5
10. Cool: Untappd, an app to track your Beer check-ins, built with HTML5, CSS and PhoneGap
