Research:Ideas/FlaggedRevs unregistered users engagement
Flagged Revisions is enabled on several projects, with varying configuration and outcomes. On the Russian Wikipedia, 94 % articles are reviewed, but 16 % of those are outdated, with an average wait of 366 days for those backlogged edits; average wait for edits by users that have not logged in to be reviewed is 12 d 15 h; the median is 13 d 4 h (w:ru:Special:ValidationStatistics, December 2014). The latest revision is shown anyway, whether reviewed or not, so the main direct consequence is the display of a blue "warning" on a large chunk of articles (about 180 thousands).
An example notice is «4 changes in this version are pending review. The stable version was checked on 6 July 2014» (from ). It links a combined diff, w:ru:Википедия:Патрулирование, a permalink and a link to logs. We know the project page receives about 5 thousands views per month, but not how many from unregistered users; we don't know how many clicks the other links receive; we don't know how many logged out users edit, register or review after seeing such notices.
