I find the grafting of cocoa onto javascript a bit stomach turning. Its like watching a man read the news to you on TV. Different mediums require different methods. I don't think anyone has really gotten this right yet. I agree jQuery isn't the whole solution, I don't think Sammy.js is the whole thing either. But I do think there will be something built on top of this stack. I have started to try and create something like this http://github.com/voidfiles/BHive .
