This is an interesting article from the BBC about how people in Iran are finding freedom on the web where they can't get it in 3-space. Very cool. Let's hope that the Iranian government continues to leave internet access and the web free and uncensored. Heaven knows the people there can use a way to express themselves unhindered.
I don't know much about Iran, but what I do know scares me. I had friends, a brother and a sister, in college who were Iranian. Their family had converted to Christianity and left Iran when they were both young, I assume at least in part because of the danger that decision had put them in. My friend Nagmeh had a scar on her forhead where she had been marked in case she ever tried to return to Iran.
