In order to have a blog, if this law is really issued, its owner must be registered to the ROC (Registro degli Operatori di Comunicazione), and must have a registered journalist as "Chief Editor".
I know this sounds like a joke, but it's not. Not a real law for the moment, but has been proposed in August and seems like it has been approved by one of the government commissions.
