My Zet's are a link directly to their location in GitHub.
To keep people on the page and reduce the load times it should be possible to do either,
grab the raw text from github and generate a single page with it
pull out text data from zets.json and load that via a shortcode
Either of these would keep zet data on the site and significantly reduce the load times. Plus its jarring linking directly to github due to the page transition.
