Censorship and surveillance
I've just posted about the Iran elections over at the Bluestocking Blog. I also came across a few stories yesterday about new developments in Australia's crazy 'net censorship, including news that the blacklist now includes several sites from Wikileaks, and that ACMA will fine people who link to sites on its (secret) blacklist.
As I've said before, the whole Clean Feed is a terrible idea, and students, researchers, and academics should be particularly concerned about it. If you don't know about it already, there are plenty of ways to get informed and get active.
