I'm also super interested in this topic.
@Bettina no there are no Js planned yet for the future. We made the last on May(i think..)
From my personal experience and for what i can see from the Js follow up jQuery seems something TODO. I know how you think/feel about Martin but i think if we wanna help people to really use and understand js now, we should show them about it
Many people asked for it and have to deal with jQuery plugin in their project so make totally sense.
Ajax, more or less the same. I mean, i don't know how many "beginners" deal with it but is something you need to know and you will find on your own after or before.
And backbone will be awesome but i really think it will be possible just depending how the workshop is structured.
I personally really like: focus on the topic separately.
Or we can do as we are doing for the Css advanced. Give a curriculum with lot of different topic and people can choose which one do and try more than one but i'm not sure it works well here (because topic need more time to understand/try out)
