YouTube is so sensitive to its new role as a means of exposing oppression that it's suspended its rules against posting violent content. Of course, finding stuff on YouTube can be a chore, which is why there's Citizentube (don't go there unless you want to see people dying and getting their heads kicked in). Meanwhile, The Huffington Post has had bloggers covering the whole thing 24/7, and has put together an aggregation of Twitter feeds.
CNN doesn't have to worry about covering Iran - it's taken care of. They can now focus their precious resources on the stories they really care about.
