Karma question

I decided to post this here since it really isn't part of Vb --

What exactly is a karma hack and what is it's benefit?

wluke already made this hack for his own board and promised to released it for everybody after v2 will be released.
Anyway you can find an explanation of what the Karma Warn/Praise hack is going here. Note: Do not care if that version was made for UBB (bleah!) 'cause the features are nearly the same.

Karma is a way of rating users through their posts. This allows a more accurate rating and eventually will inspire trust for your most prolific and knowledgable users from newcomers. In a community based around knowledge or finance this would be a very good thing. For those communities that are purely community oriented karma is not as needed.

In my system, I allow comments on the Karma and these comments will help members improve over time. I felt comments were necessary because often times you would add something that doesn't really warrant a one-line post or doesn't add anything to the conversation.

Karma provides a way for members to police themselves and keeps moderaters from having to use heavy handed tactics to keep things within the guidelines.
