We receive The Email from Netflix! We are the current "top contender" for the Grand Prize!
A hectic 24 hours! After frantically searching for some last
minute 'secret sauce', we made our last submission just an hour before
the contest closed. Our improvement of one-hundredth of a percent
was matched shortly afterward by The Ensemble, who remain ahead of us
on the public leaderboard...
: A coalition of our top competitors formed to create The Ensemble
, and became the second team to pass the 10% barrier, leapfrogging us into first place on the Quiz Set. This created quite
in the blogosphere
! Congratulations to our fellow competitors.

him on the Netflix Prize work and his Best Paper article at
KDD. Here is

More exciting maneuverings on the leaderboard as new coalitions
have been created, and are challenging the 10% mark.
We've still got a good lead, but perhaps less comfy.
July 7: Article in Business week
about the competition. Apparently Netflix plans some 'pomp and circumstance' for the winner.
MediaUnbound is running a series on the Netflix Prize in the final 30 days called Countdown to 10%
Coverage on John Langford's Machine Learning Blog. Of note is the first commenter, who points out his/her views on the ML contributions of the contest.
There is a fascinating story unfolding, as other teams attempt to
collaborate to challenge our current score before the end of the 30 day
"last call". At least three
groups are gathering up colleagues on the leaderboard to see where the
benefits lie. This is great! It is this collaborative
spirit and friendly competition that has made this endeavor so
enjoyable for 2.5 years. See you at the finish line!
