Yet another interesting beta creation is rolling out of Google today. This latest tool allows users to view personal statistics concerning their Google services usage. Users who choose to opt-in are sent a personal report every month.
Statistics tracked in the Account Activity project include emails sent, received, and most contacted addresses. Statistics related to your search history are also included if you have opted in to that feature as well. Location related statistics including Latitude visits and areas that you've signed in can also be found in the report.
Google asks users to submit feedback through their reports. They also promise to integrate more Google services as the project moves forward. Anyone who would like to see their own personal Account Activity can opt-in at the source link.
