The only real effect of this sort of behaviour is to make the state media look ridiculous, since people can easily find out what is going on from satellite television, the internet and Egypt's non-state media. Some of the best day-to-day coverage comes from a group of unpaid bloggers on The Arabist Network.From Cairo with Love is also mentioned, and Samir Ragab gets his comeuppance.
It should be noted that Brian's site Al Bab was one of the first websites discussing the Arab world and was one of the inspirations for Arabist.net. It has a round-up of his favorite blogs here.
Update: I just checked the server logs, Arabist.net has just broken the 50,000 visits barrier (51,688 to be exact) for June with an increase of over 20% compared to May. Many thanks to all the readers, and especially to Josh and his dedicated (and sometimes risky) blogging while Charles has been away and I've been swamped with work. I think it also shows that the world at large is taking an interest in what's happening in Egypt at the moment, and that can only be a good thing.
