See source for this, specifically the jsbin.metadata.summary: http://jsbin.com/vequl/1/edit

[stale]

This issue has been automatically marked as stale because it has not had recent activity. More importantly, jsbin has been undergoing a massive refactor by Remy, and a large number of issues have been resolved, but with the growing 600+ open issues, the Stalebot (me), has been brought in to try to manage the issues.
Keep an eye on jsbin.com blog posts and the @js_bin twitter account for updates on the new version of jsbin ❤️
It will be closed next week if no further activity occurs. Thank you for your contributions.
