I went to SXSW in 2011. God, that was awful. I mean, I only went because my publisher wanted me to promote the book and the organizers invited me and it seemed silly not to go, especially for a relatively unknown first-time author. This is just not my cup of tea; the fewer such events I do on an annual basis, the happier I feel.

The goal of privacy is not to protect some stable self from erosion but to create boundaries where this self can emerge, mutate, and stabilize.

I draw a distinction between freedom of the internet and freedom via the internet. In the first case, it's making sure cyberspace is not over regulated and people can say what they want without fear of repercussions. But that's different from this freedom via the internet notion, which is often touted by all sorts of conservatives and neoconservatives who want young people in the Middle East and elsewhere in the world to use Facebook and Twitter and then go oppose their governments.

If you want to plan a revolution, you never do it in public - the authorities show up and arrest everyone.
