Michael Yon was a green beret and now spends his time as a journalist/writer. Currently he's in Iraq as an embed - for his second tour. his accounts of iraq from the ground give better insight into what is going on over there better than any mainstream media organization. I've enjoyed his writings for some time now and if you are interested in military blogs, he is someone to read.

in this article he says something to the extent of bloggers being either freelance journalists with original content (like him) or people who simply steal from other news sources and post it on their own blog, sometimes giving the impression that it may be their own content - effectually plagiarizing
