Observation
MoinMoin is Ubuntu's primary wiki for documentation. It is probably the most actively used MoinMoin wiki I've seen.
They have documented particular difficulties on these page:
http://wiki.edubuntu.org/BetterWikiDocs
http://wiki.ubuntu.com/wiki/MoinEnhancements
The correct way to discuss about moin improvements is to make a FeatureRequest page or a MoinMoinPatch page (if there is already code existing).
