Alot of sites, includeing GovLoop, use recognition as reward. Here I would like to add two levels of recognition.
1) Posts – based on the shear bulk of their posts regardless of content.
2) Popularity – people vote and pick their ‘fav” member based on value and quality of posts.
How to do that on a wiki? One is the content put on the wiki with out names. Second is the discussion or wiki guidance. The maintenace – this wiki page needs expanding, needs citations, needs links to the definition of this term, etc.
Just a thought.
