Special:Insights seems to have started working in some wikias, but not others. For example this wikia still has a blank Wanted pages which is practically impossible (see Special:WantedPages) given that nobody seems concerned about maintaining those dead-end links. Maybe the cache is expiring on different wikias at different rates.

It is even odd that  insights is enabled on community central. It is not like a regular wikia, and admins only seem concerned with  deleting spam, blocking some users, interwiki links, answering questions and making the occasional random post or warning users.

It seems that  the term "lead by example" doesn't apply  to community central.
