[zwimer]

Loading http://lab.lepture.com/github-cards/ in a vanilla browser with no extensions at default settings (Safari) seems to load a page with mutable text boxes that doesn't actually do anything.

[Error] Failed to load resource: the server responded with a status of 404 () (widget.js, line 0)
[Error] Refused to execute https://lab.lepture.com/github-cards/widget.js as script because "X-Content-Type-Options: nosniff" was given and its Content-Type is not a script MIME type.
