Tweeting in "Tehran"

I've just joined what I'm told is a global movement all over the Twittersphere, and struck a blow for democracy and religious freedom by changing the location on my Twitter account from Des Moines, Iowa to Tehran, Iran.

The idea is that if people all over the world do this, it will make it harder for the religious police in Iran to keep track of the tweets that actually do originate in Tehran.

Juvenile? Futile? Perhaps. But satisfying- and fun.
