Ethan Zuckerman, who works at Harvard Law School's Berkman Centre on Internet and Society, holds forth on how Web 2.0 has spurred online activism, and that's what good for posters of porn and cute cats is also good for dissidents.

The nut graf:

With web 2.0, we’ve embarced the idea that people are going to share pictures of their cats, and now we build sophisticated tools to make that easier to do. as a result, we’re creating a wealth of tech that’s extremely helpful for activists. There are twin revolutions going on - the ease of creating content and the ease of sharing it with local and global audiences.
