It is fascinating to see the Internet (and in this case Facebook) displacing the multi-billion(trillion?) media estate. I remember the dot.com bubble where the media claimed that statements that the Internet would make them obsolete was crap. 20 years ahead of its time I guess.

The policy question is similar to the phone system one, is it in the people's best interest that their be a standard phone system? And if so, can you regulate it sufficiently to avoid abuses? Those were the questions surrounding the original Bell network in the US. What does a monopoly look like in the Internet world, and do we, can we, regulate it? Pretty important questions.
