Script to get reasons:

reasons = new Array();
function next() {
  $.getJSON('http://c0.xkcd.com/xb/feed').done(function (data) {
        console.log(data.prompt.reason);
        if (reasons.indexOf(data.prompt.reason) == -1) reasons.push(data.prompt.reason);
  });
}
next();
setInterval('next()', 10000);

I've determined 10 seconds to be the time you keep getting the same data, so there's no reason to poll the server more frequently than that.

You can check on the reason variable at any time.

I'm only interested getting in the reasons, feel free to adapt this script to get whatever else.
