Apple ramps up involvement in SproutCore
What makes SproutCore so different? Charles explains:
"SproutCore is for applications that want to adopt this new 'thick' client model for building apps on the web. If you are creating static pages with a widget here and there, then SproutCore is probably too much for you and another framework such as YUI, Dojo, or Mootools will do the trick. If you have built desktop applications in the past and you would like to bring that same experience to the web, however, then you will feel right at home with SproutCore."
Some interesting developments since WWDC (as publicized on the SproutCore blog) include the release of version 0.9.10 of the framework, publication of a bundle for TextMate, and creation of a wiki and Meetup group.
