Random notes:

• For IE7 the focus was on security, IE8 = user experience.
• The IE guy is explaining about how interoperability hurts innovation, because too much time is lost in fixing those (can’t help but getting a big DUH! feeling).
• He explains how there’s a lot of content on the web, that depends on the buggy behaviour of older IE versions.. so there’s a challenge to solve. IE8 will introduce a compatibility mode, a lot of information with big opionion pieces from both people who like or hate this can be found on A List Apart Look for version targetting.
• Looks like they created a Firebug-like tool for IE..

HTML 5

• Making the back button work, using HTML5 hash function? Can’t actually find any info on this and I think this can be implemented today?
• HTML Connection events .. very cool, javascript can catch an event if the internet connection is gone!

OpenService

Seems to be about deep browser integration.. Subscribing to Webslices.. Seems to be a mini i-frame integrated into the toolbar.. Examples are shown of facebook status updates and Ebay auctions..

To integrate, add the ‘hslice’ css class to a div.. If you go to Your facebook homepage, and look at the source, you’ll notice there’s ‘hslice’ css classes.
