Combined with the shadow profiles question by Congressman Lujan from New Mexico, some of these questions are getting closer to what people need to know and understand. Unfortunately, a lot of the rest of questioning seems like blind man's bluff / Marco Polo [0].
It'd be nice if Congress can be asked to host a debate between subject matter experts in the privacy domain (who are knowledgeable and can effectively communicate this knowledge and their concerns to lay people) and tech company C-level executives like Zuckerburg.
2:50 PM EDT: Congressman Duncan from North Carolina is going to give Zuckerburg a small copy of the US Constitution.
