Are bloggers journalists?

San Francisco Chronicle columnist Debra J. Saunders has reignited the debate over whether or not bloggers are journalists. Her recent column argues that Josh Wolf, a blogger who has been in jail for over six months for refusing to hand over a video of a violent protest to a federal grand jury, “is not a journalist” but rather: “a blogger with an agenda and a camera, who sold a ‘selected portion’ of the video of the demonstration, which left a San Francisco police officer with a fractured skull, to KRON-TV.”
