What will be creative common public domain license for a digg like site.(social bookmarking site). Actually at the moment their old tool for public domain license has expired.There are more options in public domain license.Is that a right method for placing CC license for user content, or just place a Term of use document.
If a user shares links and videos on a site(just like a digg web site), What will be CC license that describes copyright or no copyright at all. Where should I put this question in stackexchange, if this is a not a right place. This website explains about digg website footer has link to CC0 license(creative common) but it is 2 years old and digg has removed the link.
