The Data Liberation Front (DLF), a left-wing guerrilla group of Googlers, has finally launched its first service: Google Takeout. Just sign in, select which Google services you want to back up, and then click Creative Archive. Each of the services will be tidily backed up to a zip file in open formats that can be imported into other, non-Google web services. To start with, Takeout only supports the easy exporting of Buzz, Picasa, your Google Profile, Contacts, and Circles — Google’s recently-launched Facebook competitor — but the eventual plan is to provide easy exporting for every Google service.

If you haven’t heard of them before, the DLF is a group and a website that helps you extract your data from Google’s web services into open, easily-transferable file formats. You can then take your email or docs or RSS feeds and import them into an installed program, or Microsoft or Yahoo’s equivalent web service. Curiously enough, though, the DLF is an engineering team at Google. The idea isn’t that they want you to transfer your data away from Google — they just think it’s important that you can. It’s basically Google’s way of showing that the data it holds in its massive database is yours, and you’re free to do what you like with it; it’s the embodiment of Google’s corporate Don’t Be Evil motto, in other words.

The timing of Google Takeout is highly suspect — but in a good way. Just last night, Google launched Google+, along with its Facebookesque Circles service. Facebook makes it notoriously hard for users to extract their data and photos, while Google Takeout and the Data Liberation Front will ensure that Circles remains very open. Having said that, Facebook recently crossed the 750 million user mark, and scant few have complained about the difficult privacy controls or the inability to export data in open formats. Circles will undoubtedly be popular among certain groups — and Takeout is definitely a juicy sweetener — but whether it can actually draw significant numbers of users away from Facebook remains to be seen.
