The one year death anniversary of blogger and journalist Omid Reza Mir Sayafi is coming around and the OR318 movement is quite active, raising awareness regarding not only Omid's  death in an Iranian prison but also the risks bloggers take when they decide to write.
On their website march18.org they have gathered blog posts, videos and photographs around freedom of speech, and also have active twitter and facebook groups.
