... Google is currently offering the Prez's biography as its top link for the search 'failure':
They don't seem to have realized that this is not a new Google-bomb, but rather some sort of effect of the old "miserable failure" Google-bomb (and possibly also due to transient effect of Google being in the middle of an update). Or maybe they did, but decided it was worth reporting anyway ...
The miserable failure root cause is apparent from George W. Bush's biography being the top result right now for a search for either failure or miserable (because of all the links for miserable failure).
And further proof, Michael Moore's site (similarly Google-bombed) appears as a result for all three searches.
I suspect some of this will change in a few days as the Google update
completes.
[Update 9/27 - It's a long-lasting failure]
