Completed two A/B tests on English and German Wikipedias. The $testresults|results]] displayed a decrease in pageviews, but an overall increase in the number of pages readers interact with, indicating that they are more likely to explore a larger variety of topics when the feature is on. We also noted decreased usage of the back button and very low rates of disabling the feature.
