From Hossein Derakhshan's blog:
"I'm not sure if there is any Cafe for bloggers in other cities, but there is one in Tehran. Actually it's recently opened in a northern area of Tehran and Ive heard that it's quite popular among Tehranian bloggers. It's called Cafe Blog and based on the website, they held some basic technical workshops for their members. There are some photos from their opening on their website."
