The Wikimedia Foundation has been creating a new Article Feedback system,
and on Saturday 9 June from 10AM-noon Pacific time, WMF invites testers and
anyone else interested to participate in a "shakedown cruise" to test a
near-final version of the new Article Feedback system before the system is
rolled out to all of Wikipedia.
Following on May's successful test event with Weekend Testing Americas, WMF
is teaming up with the Open Source fans at OpenHatch.org
for this event. I
am hoping that having experienced exploratory testers plus people
interested in improving Wikipedia articles will be a killer combination of
expertise and interest to shake out any final issues in this critical
aspect of the Wikipedia experience.
