Karma/Reputation Plugin for Ruby on Rails?

Question

I am looking for a karma (reputation) plugin or gem for Ruby on Rails. Preferably one that was integrated many of the best practices and research around the topic of community management & development. Any recommendations?

There's vote fu.

Howver my advice would be the following : don't rely every time on plugins.
For some things that could be completely different from one app to an other, relying on a plugin can sometimes makes things harder to implement.
