Since starting at Public Knowledge (pk) I have been asked at least 20 time what is PK and what do we do. Here is my 1 min elevator speech for PK feel free to make comments:

Public knowledge works to ensure that public interest is given a strong voice when creating intellectual property, access to knowledge and telecommunications policy. Traditionally these polices have been legislated or created by the courts without bring all stake holder to the table, specifically the public has been left out. This is where PK comes in to represent users interests as users become the new generation of participatory creators. PK strives to create more access to information and ideas through advocating for logical policy that values innovation and openness.

If given more time and the person has interest I will continue by highlighting there work in copyright on fair use or orphaned works, on net neutrality or in terms of service dependent on the audience.
