Google announces 'Account Activity,' which tells you what you've been doing.
OK, this is awesome. Google just announced a new service called Account Activity.
You sign up for it, and Google will send you a monthly report full of stats on your own Google account. It's a kind of a "quantified self" tool for stuff you do on Google services like Gmail, Search and YouTube. It also shows you some data on how others use your content -- for example, it will say how many people have watched your YouTube videos.
Best of all, it will tell you if "you" have been logging in from, say, North Korea so you can take action and change your password or whatever.
