Hi,
Hi Dimi,Stephen and I wrote a guest post for EFF about the importance of the public domain for Wikipedia last month: https://www.eff.org/deeplinks/2014/01/wikipedia-shows-value-vibrant-public-domainYou may want to reuse some of that discussion to expand on the section on the social value of the public domain and open licenses. I think that concrete examples would help make that section more persuasive.
