Blogging in Iran

I found it interesting that blogging is so popular in Iran. Blogs could provide a medium to express ideas anonymously that would get people in trouble otherwise. Though it was mentioned that some people were arrested for their blogs, I think it should be possible to remain relatively anonymous. It is also interesting that Iranian conservatives are embracing blogs, especially since the potential anonymity does not benefit them as it does liberals/reformists. Perhaps the popularity of blogging in Iran indicates a desire for change that is more widespread then the government portrays.
