White blogule to deep throats

If W. Mark Felt actually is Watergate's "Deep Throat", the best kept secret in journalism has come to an end.
What puzzles me is first the timing of the disclosure... right after the "flushed Quran" scandal (which, as I suspected, should never have been called the "Newsweek scandal") : just to remind the not so courageous guy who leaked the Guantanamo mess before retracting the whistle blower can be the hero.
What puzzles me next is the paper releasing the scoop, "Vanity Fair" being a joke on the media exposure. Exposing himself as Deep Throat to the mass media mirrors wasn't about vanity - the guy is 91 and just wanted the truth to come out. What wasn't fair was the necessity to hide for telling it in the first place.
