Oddmuse is the WikiEngine? developed by AlexSchroeder, aka. OddMuse. CommunityWiki also uses Oddmuse.
Oddwiki is a MotherWiki that also uses Oddmuse. Unfortunately Oddmuse and Oddwiki seem to be too similar, and now people confuse the two.
While looking around for some material to support a WhyWiki? page, I stumbled on this. Given our recent decision to standardize on OddMuse for Server-Side wikis, it just seems appropriate to add a bit of an “endorsement” for OddMuse to this page.
