A little over a month ago, Google announced they revised their doorway algorithm and updated their guidelines around doorway pages.
But watching the space for a month, all I see are webmasters asking if it really launched or if it was still in the queue to launch.
Google's John Mueller was asked if it launched by Joshua Berg in a Google+ hangout this morning and John Mueller said "I believe that has rolled out, yea."
He basically did confirm that the doorway algorithm did launch.
He said this at the 18:55 mark in the video, here is the embed with the question and answer so you can watch yourself:
I should note, I track a ton of forums and all the threads I've seen on the doorway pages, both in whitehat and blackhat forums, still have people asking if it really launched.
Forum discussion at Google+ & WebmasterWorld.
