Turns out I'm too tired to do this tonight. I will try to do this over the weekend or on Monday. I'll try to ping each of you when there is an RSS feed.
In the mean time, we'll tweet about every issue on https://twitter.com/hackerschool, but I know that Twitter isn't RSS and that subscribing to our Twitter feed in order to get the 4 tweets per year that you want to see might be silly.
