That would be even cooler to check to see if the github pages even exists before navigating there, but there is the Access-Control-Allow-Origin issue. I figured since it was github.com and github.io, they would allow such requests

var xhr = new XMLHttpRequest();
undefined
xhr.open("GET", "https://jlord.github.io/sheetsee.js/", false);
undefined
xhr.status;
0
xhr.send();
XMLHttpRequest cannot load https://jlord.github.io/sheetsee.js/. No 'Access-Control-Allow-Origin' header is present on the requested resource. Origin 'https://gist.github.com' is therefore not allowed access. VM1046:2
NetworkError: Failed to execute 'send' on 'XMLHttpRequest': Failed to load 'https://jlord.github.io/sheetsee.js/'.

Interesting thought. You could circumvent the cross-origin issue by assuming that index.html exists on github.io if it exists on the github.com domain in a gh-pages branch. Have your xhr check that the gh-pages branch exists, search it for index.html, and render the appropriate path prefixed with ____.github.io.
