This framework looks really cool, but "built by Google" is a misnomer. Software like Closure, or the gold linker - these deserve to be called "built by Google"

This framework looks really cool, but "built by Google" is a misnomer. Software like Closure, or the gold linker - these deserve to be called "built by Google". Internal tools, battle tested over years, released to the public. Angular and Polymer are more like what I'd call "technologies by Googlers".
