FlaggedRevs is now actually live on de.wikipedia.org :-). Congratulations and many thanks to _everyone_ involved in getting us to this point. In a nutshell, FlaggedRevs makes it possible to assign quality tags to individual article revisions, and to alter default views based on the available tags. In the German Wikipedia configuration, unregistered users will always see the most recent version that has been checked for vandalism, if any such version is available.
Aka hacked up a nice script that shows how many pages have been "sighted" (basic vandalism check) on the German Wikipedia:

Given that FlaggedRevs has just been live for a day or so, a review rate of 4.41% is quite impressive! Kudos to the de.wp community for its pioneering role in this important experiment. As a reminder to other wiki communities, the extension can still be tested in the Wikimedia Labs at:
Since the FlaggedRevs extension can be very flexibly configured, it will be up to individual communities to determine what the best roll-out strategy is. From our point of view, it's best if communities self-organize to make decisions around the use, and that they file requests through
https://bugzilla.wikimedia.org/
which point to a decision on their community to enable the extension. But, in the least intrusive possible configuration, FlaggedRevs is essentially a very powerful change patrolling tool, and I could see us phasing it in like any other new feature.
