The explanation could be better, but I really like the idea. It punishes you for not updating your dependencies and for having too many direct dependencies.

The explanation could be better, but I really like the idea. It punishes you for not updating your dependencies and for having too many direct dependencies. But it doesn't punish you for indirect dependencies (that you have little control of), or libraries that are "done" (since it compares to the newest stable release, not the current year). A sensible balance. Maybe one could write a browser extension to display the libyear of GitHub pages?
