After all of the issues with Facebook's terms of service and concerns over who owns user-created content on the site, it's interesting to see Creative Commons enter the Facebook arena with an app. Installing the Creative Commons app lets users display the CC badge of their choice on their profiles, indicating the licensing terms they want to use for their profile content. This could be a big step toward bringing Facebook up to speed with more legally progressive social networks like Flickr in terms of content ownership and licensing. It's just a shame that the idea didn't come from Facebook itself.

There are still a few limitations on the CC app at the moment. For example, you can't choose a license for each of your photos individually, like you can on Flickr -- the CC badge just applies to your whole profile. It will be interesting to see how Facebook responds to this development -- by introducing system-wide CC-licensing options, I hope -- and whether the app gains a strong foothold with users.
