As a young entrepreneur, I had the chance to be invited. Maurice Levy who was in charge of setting up the event did a great job in the organisation: attendees were offered food from LeNotre and there was no major problem which is rare in the kind of big events.
In his introducing speech, Nicolas Sarkozy war clear: the Internet is a great strength for our economy and its global approach changes the way things used to be (in a good way). But this revolution has to framed by the states and the governments in order to make sure that it stays fair and moral. As he doesn't want to slow down the evolution, he wants the main actors of the Internet to take part to the political discussion.
That's the theory. Because in the end the discussion panels were more focusing on how to defend or promote their own services than elaborating a real discussion on what role the governments should have.
Finally it was a way to clearly shows that our leaders feel concerned about the Internet. It's a very visible event, but there won't be any effective decision concluded.
Obviously people from the Internet industry took the opportunity to network and meet some interesting people. We even had on open Mike Butcher session to introduce "real" startup. It was basically startupers shouting what they were doing to who ever wanted to listen....
