Starting January 1st, Iranian bloggers are expected to register (link in Persian) their blogs with a governmental agency and receive a registration number to put on their websites, my Iranian sources tells me. Apparently, failure to comply within the two months deadline will result in filtering. This has also been reported here before, but there are still a lot of unclear issues.

I wonder how many will actually register, and if this apply also to Iranians outside Iran? Only if they write in Persian? Will they filter everything that is not approved, or did they invent this to have an excuse to censor arbitrarily?
