I run a number of personal blogs, and like all bloggers I am obsessed with statistics (who doesn't want to know how unpopular their thoughts about their cats are?). Google Analytics is a great, free service from Google that gathers a number of stats from any website onto which you add Google's magic code.
Why am I blathering on about Google Analytics on TUAW? Because Dashalytics is a cool widget that puts your Google Analytics stats right in the Dashboard (to make the obsession even easier). You can even use multiple instances of Dashalytics to multiple websites.
