I’m a big fan of Webkit. Although I had been a die hard fan of Safari for a while I’m now using Google Chrome as my primary browser. The great thing about Chrome is that it too uses the Webkit rendering engine. I’ll catalog my reasons for using Chrome in another post.
The next version of Webkit that will be released will come with a new version of the Web Inspector, a tool used by Web developers to "inspect" an already-loaded Web page for debugging, testing, etc., that has some really great new features thanks in part to Joseph Pecoraro.
I love that I can choose either Safari or Chrome and I will still benefit from this update.
