Digg has just upgraded the license for all of its content - titles, descriptions, comments, everything - from public domain to Creative Commons Zero (CC0).

Under the public domain license, the content was already free for anyone in the US to use for any purpose. By switching to CC0, this content is now also public property internationally. The Internet is getting more and more fragmented each day, with copyright laws altering our entire online experience depending on where we're physically located. So, although the license change may not seem like much, it's a welcome change and a nice gesture from Digg.

Digg has also updated its Terms of Use to reflect the changes; the new wording can be seen in Section #6 of the TOU.
