It's interesting that much of this progress is able to occur because the various competing teams (Google, WebKit, Mozilla, etc.) are all doing their work out in the open:
This work is delightful for multiple reasons:
- As a user, I can continue to anticipate better browsers, faster web pages, and a happier overall experience
- As a programmer, I can continue to benefit from learning about all these different techniques
Nothing but goodness in all directions!
