According to the BBC, the Committee to Protect Bloggers has deemed tomorrow Free Mojtaba and Arash Day, and is asking bloggers around the world to participate in a variety of ways. (Bloggers Arash Sigarchi and Mojtaba Saminejad are currently in prison in Iran.) And while I have to tell you that I know far less about the Committee and its efforts than I probably should (just what Jeff Jarvis tells me, in fact), it would certainly seem to be a more than worthy cause.
