We've only been running for a few weeks but we've got about ten kids showing up every week. So far I've shown them some demos of things like using Google maps in your own software, making your own maps with TileMill, browser based games with Crafty, and phone call and SMS stuff with Twilio. They seemed to respond positively to all the demos but were very excited about the Twilio demo. I'm not surprised, because I also thought the ability to type something into a text area in the browser and then receive a phone call with that text read to me, is pretty sweet!
Most recently we started doing some basic HTML. Pages, images, links, etc. The kids were simultaneously making jokes about how simplistic it was ("oh wow, text on a page") and super excited to be creating something ("look I made it say something different", "cool, let me try!").
So basically what I'm saying is that if you have the opportunity, stop just "spreading the word about programming" and actually work with some kids to teach them something. It's only been a few weeks, but already it feels like very fulfilling work, and hopefully it will make a difference to expose these kids to the what's possible for them to do earlier than they might otherwise encounter it.
