Really excellent overview of how to debug and inspect CSS, HTML and JS code effectively with Chrome. A year or two ago I was a die hard (Firefox) Firebug user, but I’ve come around to the Chrome tools as my preferred toolkit for web development.
Personally my only point of contention is with the author’s support for Chrome Canary as his development platform, of which i’ve run into serious bugs, crashes and rendering problems. Instead I prefer a more moderate approach by running the Chrome Beta as my main browser. I find it’s highly stable yet you still get many of the new development features far ahead of the default Webkit releases.
