I think guys like BT are missing the real story in Michael Yon and others like him. These guys are living proof of the complete collapse of U.S. government credibility. The government can't get its message out effectively because nobody believes them any more. They have been caught in lie after lie, and now only a shrinking hard core of true believers bordering on "fruitcake" status pays any attention at all to anything they say.
Hence the Michael Yons of the blogosphere. Without getting embed permits ('cause they're "rebels!!") they nevertheless manaage to get all the benefits of an embed, accompanying the troops into combat, skipping in and out seemingly at will, and still manage to write "angry" blogs denouncing administration "blunders" just so long as the "blunders" they so freely denounce are related to peripheral items such as the media wars or past policies. Of course, they will never denounce the PRESENT policies, or the PRESENT military leadership, because that's really what they're tasked with selling to the public.
Of course, in the end, their lies and bullshit will be exposed as were the administrations, and they will become "yesterday's men," but another few desperate months will have been tacked on to the Bush administration's losing effort to subdue Iraq.
