It's awesome that TechCrunch are giving back to the platform they use and open sourcing this plugin. Sites with massive traffic like TechCrunch need to solve different problems to the average website so it always great to be able to see how others tackle theses issues.

It's something that we try to do at our agency whenever we can, and in some cases we were able to commit code that was developed on bigger projects back into popular plugins that were used.
