An interesting video from Matt, doesnt really give us any more clues than what we already knew - its an algorhythm change.

Im sure we all have 101 questions that he didnt answer! My main one would be does the new algorhythm require a complete reindex of the long tail - ie are they re-crawling sites in the long tail because of a new ranking factor which was not previously measured in earlier crawls.
