I'm an 11th grader and for Hour of Code we have just recently graduated from block-based programming... to HTML. I personally just either do my computer programming homework or work on a side project, but I don't believe that the Hour of Code is too useful to anyone else.
I feel like someone needs to make some sane Hour of Code activities for high school students and do things like presenting on it at conferences and podcasts. From what I can tell from multiple years of presenting similar things, those are some of the best ways to get an idea to public school technology administration.
