looks good to me. The only thing I have concerns about is wether we should try to make fine grained help categories, which probably will mean that we will have a lot of them. Or if we should just keep a more general one and add more when we see a need for adding a more specific one.
Currently I would be having troubles where to put anything ember related except cli, routing, testing and ember-data stuff. Where do questions about controllers, components etc. go?
edit: just noticed during writing that post Adding ember weekly to the emberjs site? that we probably should also have a category to discuss the emberjs website including docs etc. If meta stays a place to discuss the forum, this does not really fit anywhere. However, having that said, I could have just opened a issue over at github as well, which probably would have been just as good
