I hope it could be useful to provide links to the best articles about it, which have good, technical contents.
Thoughts on Blink from HTML5 Test is a good summary about history of Chrome, WebKit, and puts this recent announcement in context. For even more context (nothing about Blink) you can read Paul Irish's excellent WebKit for Developers post.
Peter-Paul Koch (probably best known for quirksmode.org) has good articles about Blink: Blink and Blinkbait.
I also found it interesting to ready Krzysztof Kowalczyk's Thoughts on Blink.
Highly recommended Google+ posts by Chromium developers:
- Justin Schuh talks about security improvements made possible by Blink
- Ben Goodger explains layering and embedding of the new engine
- Charlie Reis is excited about out-of-process iframes
If you're interested in the technical details or want to participate in the discussions, why not follow blink-dev, the mailing list of the project?
