Google’s Data Liberation Front has announced the launch of Google Takeout, which it calls its “first revolutionary product”. Another way of putting it would be, a way to take your data out of more than one Google product at a time.

At DataLiberation.org, users can already browse through Google’s list of products and see detailed instructions for each one about how to “escape” from any of them. This list includes: AdWords, Alerts, Analytics, App Engine, Apps for Businesses, Blogger, Bookmarks, Calendar, Chrome Bookmarks, Contacts, Docs, Finance, Gmail, Health, iGoogle, Maps, Notebook, Orkut, Picasa, Reader, Voice, Web History, and YouTube.

“Since we began in 2007, the Data Liberation Front has been focused on one thing: making it easier for you to take your data in and out of Google,” the team says. “Our first step was to make it easier to get your data out of our products, one product at a time. While we’ve made great progress on this front, we’ve been on the lookout for even better ways to let you take your data out of Google.”

Right now, you can only use Google Takeout to take data out of Buzz, Contacts and Circles, Picasa Web Albums, Profile, and Stream, but Google says more products will be added as time goes on.

Google also directs users to the settings menu in Google+. Of course, you have to have an invite to even use that at this point.
