Henri Bergius – Embrace And Extend:

"These [SPDY, Dart, Schema.org] - together with WebSQL, NaCl, WebM and WebP - mean that Google has active efforts to replace practically every layer of the web (except HTML itself) with something of their own design.

The way all of these were introduced bears strong reminders of how Microsoft tried to embrace, extend, and extinguish the web in late 90s."
