DJ Patil, the US government's chief data scientist, made a call for comments on data ethics in his keynote and in a follow-up discussion session.

Hadley Wickham, RStudio's Chief Scientist and prolific author of R books and packages, conducted an AMA (Ask Me Anything) session on Reddit this past Monday. The session was tremendously popular, generating more than 500 questions/comments and promoting the AMA to the front page of Reddit.
