      Reviews of cdnjs and jsDelivr
      Review ofcdnjscdnjs

      CDNJS used to be a viable resource, and a great idea. Unfortunately, three years later, the maintainers have added so much cruft and useless layers of bureaucracy that makes it so difficult to add new libraries, that contributors are walking away rather than deal with the technical issues and arrogance of the maintainers. I'm sorry to say that the useful days of CDNJS are gone.

      Combining the speed and reliability of multiple CDN's (plus additional servers) - this is the future of content distribution
