Recently Digg made some changes for sharing its content and now some changes also come up with licensing. All of the content on Digg which people post has been licensed as public domain until now. Comments, story titles, story descriptions, and all of the other user-contributed content on the Digg site are explicitly put into the public domain so that others can do great things with them. For sure this is good for the internet and good for society. good for all.
As of today, Digg have taken that one step further by upgrading the public domain license to the Creative Commons Zero (CC0) license. The CC0 license expresses that content posted on Digg is public domain even internationally. Previous public domain license was only clear within the USA.
To reflect this change, Digg also updated the Terms of Use agreement.
"By creating and posting Content to Digg, you warrant that you own all rights to the Content, agree that the Content will be dedicated to the public domain under the Creative Commons Public Domain Dedication, available at http://creativecommons.org/publicdomain/zero/1.0/ and that you will not object to the use of the Content by Digg in any context. To clarify, the above does not apply to the Content on external sites linked to by the original submission."
See Section #6 of the TOU Digg also updated the footer notice.
It's a minor point maybe, but it reflects good intentions of Digg, with new license its more flexible and easy for user to contributed content without any restriction. Good to go Digg
