Reputation is used to provide feedback for posts (regardless of how constructive the feedback may be), wage wars, and form underground mafia-style crime rings where the wealthiest members control everything.

My doubloons sit untouched and unseen every single day. But with reputation, I could click the User CP link and check for new reputation messages. Whether they're red or green, it doesn't really matter. The point is it's more stimulating than doubloons. It's the middle man between public posts and private messages. Simple and quick.
