"It’s been an interesting few days for people who study social media. As the protests over election results have continued in Iran, and Iranian authorities have prevented most mainstream journalists from reporting on events, there’s been a great deal of focus on social media tools, which have become very important for sharing events on the ground in Iran with audiences around the world. I, like many of my friends at the Berkman Center and Global Voices, have spent much of the past two days on the phone with reporters, fielding questions about: - Whether social media is enabling, causing or otherwise driving the protests in Iran - How Iranian users are managing to access the internet despite widespread filtering - The ethics (and practice) of distributed denial of service attacks as a form of information warfare - Whether such online activities are unprecedented" - Steven Perez from Bookmarklet
