An excellent post on polyfills, talking through their impact, what issues people (mostly in the standards world) face.
Chock full of quotable lines, way too many to include to do the post any justice, save perhaps Lea's last headline:
Polyfills make the Web faster, inclusive, and more robust
Highly recommend reading for a greater understanding of the role of polyfills on the web.
