I would just like to see you follow up with what you outlined at the end of the article. For example, updating the URL line.
I saw the 'Mac OS X State of the Union' video at ADC. Towards the end, it was demonstrated how to set up a browswer using WebKit very quickly. Using XCode, it was easy to set up the outlets from the UI elements to the WebView; but I don't understand how the new controller mechanism was used to do the reverse: update the UI from WebKit.
It would be great if you could explain not only WebKit, but something about how this new tool works.
