summary
Comcast runs sites built with Google Polymer — Xfi and parts of X1 — and claims over 500 Polymer components in production. The talk argues web components are low‑level platform primitives (custom elements, templates, HTML imports, Shadow DOM encapsulation) while Polymer adds convenience. The team actually rewrites shared UI as reusable elements, for example a universal xc-header custom element that bundles header and footer behavior and loads via a single script tag.
