Google dives into personal analytics with new Account Activity feature

We recently saw Stephen Wolfram reveal what he called the personal analytics of his life (built from decades of meticulous data collection), and it looks like Google is now going some way towards making that easier for you to do yourself. It rolled out its new Account Activity feature today, an opt-in tool (still technically in beta) that tracks your activity across Google’s services and delivers a report each month on your internet use. That includes things like the number of emails sent and received, your most contacted email addresses, information about your search history (if you have it enabled), stats from Google Latitude, and the different browsers and devices you’ve used to sign into Google services. What’s more, that’s apparently just the beginning — Google says it plans to incorporate even more services over the next few months.
