I publish all over.
I wrote an book called On Internet Freedom.
I write fairly regularly on Slate.com.
I have written several articles for the Atlantic, two for the Boston Review, two for the New York Times (and here), and several pieces for Wired, Balkinization, and The Huffington Post.
I have published in the Harvard Law Review about free expression in the age of Twitter.
I published in Foreign Affairs on net neutrality.
My favorite of my academic articles is called First Amendment Architecture (read it). I published two other articles on First Amendment doctrine and Internet policy.
