Of course, this has some standardistas on their soapboxes about why monoculture is bad for the web, but the ease of development that it enables for developers will probably win out in the long run.
Of course, WebKit.js is fully opensource on Github, so you can go read its glorious 250,000 lines yourself. And don’t hesitate to start using it on all of your websites. All you have to do is include a script tag at the top of your page and it will be rendered using WebKit.js instead of whatever browser the user visited your site with. Enjoy!
Update: This was an April fools joke. Sorry if it got you. :)
