The Iranian blogger Sina Motellebi is free and is blogging again (via Instapundit). He was imprisoned earlier this year for his writings, but now has escaped Iran so is free to write.
The details of his saga can be found at BuzzMachine. But I find even more fascinating the story of how Jeff Jarvis' blogging about Sina's arrest became the first link in a chain of events leading to Zeyad scooping the major media.
