Hey Kevin, I read you post about jekyll and bullgit. You mentioned you got the response twice when doing the xmlhttprequest. It may be because your are not 'waiting long enough'. Maybe (certainly) the code below explains it better

gistfile1.js

var xml = new XMLHttpRequest();
//async, coz Ajax
xml.open("GET", "https://api.github.com/orgs/bullgit/repos", true);
xml.onreadystatechange = function() {
  //see this link for more info about readyState http://www.w3schools.com/ajax/ajax_xmlhttprequest_onreadystatechange.asp
  if (xml.status==200 && xml.readyState==4){
    //your code
  }
};
xml.send();
