Oh, another possible new mechanic occurred to me:

When a monk's question or answer has been flagged as "good/best" by QandAEditors, he/she would get some kind of public kudos notice. This notice would say something like:

Limbic~Region's reply was selected as a Best Answer to the question How do I convert seconds into a readable time?

How these notices are published could take any number forms. For example:

1. A message is immediately spat into the chatterbox.
2. A message is inserted near the top of The Monastery Gates.
3. A special page contains a running list/archive of such notices.
4. The notice is automatically inserted in the user's homenode.

Update: I have implemented some infrastructure for this: a function named post_notice. Currently, it does two things with the given notice message:

1. It is spat into the chatterbox, as coming from root.
2. It is added to a running list of notices at the top of The Monastery Gates.
