HTML5 and JavaScript (part 1)

Here are some ideas of things to talk about in HTML5 and JavaScript (part 1). Thanks to all who have contributed:

• There great potential in the new HTML5 JavaScript APIs: New selectors, Web storage, and Geolocation to name a few. Let's take a tour of some of these.
• JavaScript plays a big role in helping us take advantage of powerful HTML5 features. For example, with Modernizr we can start using HTML5 semantic elements event in IE. Let's explore some common techniques for this.
• Several procedural JavaScript patterns that we know and love are becoming declarative in HTML5. (Think the placeholder attribute.) How do we implement them now in browsers that don't support them yet?
