None of them pretend to be actual 'fair and balanced' newspapers.
Dailykos is a community blog. I provided links to them as statements of individuals, not news. The current value of a link to dailykos is a direct, uncensored, diary from Cindy Sheehan herself.
For those interested in her story, this has far more value than talking heads who have their own agenda.
Moveonpac had a list of vigils, and helped successfully organize over 1600 vigils across the nation, with an estimated attendance of 60,000 people.
For those interested, such sources have value, but not by pretending to be a 'news source'. It is because they were creating the news. (or debunking false reports, in the case of mediamatters.org)
AGAIN to counter the 'manipulated' propaganda point...
Cindy is PRESIDENT and Co-FOUNDER of Gold Star Families for Peace. She had the idea and took initiative on her OWN to start the protest. She contacted other people and organizations on her own.
Unfortunately for the 'talking point' of being manipulated, Cindy Sheehan has documented her own actions. I mentioned her diary on dailykos. The diary of the first day's protest has all the information about this. http://cindysheehan.dailykos.com/story/2005/8/7/171338/7578
